No, As long as you run OS X there is no need for AV software.
If you run Windows then you do need it.

Yes. There is malware written for OSX. If you are serious about your enterprise's security, or your own personal security, you should be running A/V.
Note: Many people will think that A/V is only for virii. Modern A/V suites detect more than just virii. You can substitute my usage of the A/V moniker in this document for "Endpoint Security Program" which includes a suite of scanners and utilities to protect your system.
People who tell you that you don't need AV for either an OSX machine or an iOS device are relying on poor math.
They essentially are reliant on malware authors not writing code for OSX or iOS. The only reason malware authors don't write as much code for Apple operating systems is a simple game of numbers. There are more Windows machines than OSX machines (I think Apple has about 10-14% of the market share, depending upon what source you are looking at).
Even on the mobile side, while Apple has a greater market share within the United States... globally, they do not fare as well. iOS devices account for 19% of the market share in 2013. The simple fact is that if you're a cybercriminal who writes code and you want to write code that will affect the most amount of people, you're going to write it for Windows, or Android. Or, you're going to write it for some cross-platform application like Java so that it affects an even greater amount of victims.
I'm sure Apple fanboys will say something along the lines of, "Well, I've had my OSX machine hooked up to the internet (naked) for 10 years and not a single infection!" Good for you. You are an exception for a variety of reasons. My home computer has never had A/V on it (Windows 7) and I've never been infected either. But I'm also a power-user, a systems engineer for my company and I would also never trust a normal user without A/V. Also, just because I'm a Windows user, doesn't make me a fanboy. Alongside my Windows administration, I'm solely responsible for all of the Apple devices in my enterprise. I'm listing this information solely to be upfront and credible as opposed to biased.
People who tell you that there is no malware for OSX or iOS are lying to you. Even the United States government (Homeland Security) has produced reports on infection rates that they see in regard to operating systems. If there is no malware for Apple devices, then we should expect the infection rates to be at 0%, however they aren't, granted, they aren't high but you can expect the rate to increase over time (in regards to market share). Also note that this report is from 2012.

People who tell you that iOS is natively secure; are lying. Reference the previous paragraph. It should be 0% if it is natively secure (what system is?).
If this is a home machine and you consider yourself "educated" on the dangers of the internet. You can probably get away with no A/V. Other people have suggested the use of Clam AV (read:free). Honestly, I wouldn't pay money for A/V either.
If this was a business machine with business secrets, than it is absolutely unacceptable to not have A/V. Also, if you work in the healthcare industry this is most likely non-compliant with some aspect of HIPAA.
So in short, while you can get away with no A/V, it's not the safe choice. Unless you are a power user, who understands various attack vectors on the internet (there are tons of Safari vulnerabilities) and follows a lot of the guidance that comes out from the computer security industry (don't open that attachment, phishing attempts, etc.), you should probably install A/V.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated " Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you care? In practice, there's seldom a reason to use the software unless an institutional policy requires it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
Interesting to compare this reply (little evidence, unsupported assertions, wide generalisations, dogmatic tone, frequent use of loaded terms such as "lying", "fanboys" ...) with Linc Davis's reply (factual, evidenced, with citations, balanced)
Please describe the cirumstances under which an anti-virus package will help a Mac user running 10.8 or 10.9 who doesn't blindly give admin privs to everything they download. Be specific.
Malware which affects only Windows computers, and malware which will be caught by the Mac operating system without the help of additional an anti-virus package, don't count.
Dear Linc Davis
I just read your very convincing& enlightening explanation as to why one should not use crapware.
Thing is: i have used it many times: CCleaner, OnyX , AV (Sophos&Avast).
When I first read your excellent and very sensible observations I deleted them all.
My question: did the installation/uninstallation of these apps created vulnerabilities in my old iMac, running Snow Leopard (10.6.8)????
If so, can I do anything to rectify it.
I am an ignoramus on all things computer but I certainly trust your advice.
I was thinking of installing ClamXav (not running any AV at the present time) to check if all is well. However, I am afraid that ClamXav may be a resource hog on my 2GB RAM.
I havent had any probs with my computer, I should say, but "better safe than sorry."
Many thanks.

OS X already includes everything it needs to protect itself from viruses and malware. Keep it updated with software updates from Apple.
A much better question is "how should I protect my Mac":
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.
Certain institutions, especially state universities, often require Windows PCs and Macs alike to install and maintain antivirus in order to access the Internet on their network.
So I tether to my iPhone for Internet.

Correct, and what they fail to realize is this
