Yes there was. Wordperfect 3.5e was available free several years ago. Since then, the now defunct Dataviz Maclinkplus has been good tool to transition data from Wordperfect to current word processors. http://www.neooffice.org/ currently can read many Wordperfect formats, and some other Mac compatible word processors may as well*:
If you have an Intel CPU Mac, you also have very good virtualization options for running Windows on a Mac, or using WINE to put Wordperfect on the Mac*:
PowerPC emulation options are more limited, and slower.
Is there such a thing as wordperfect for mac???
Not for OS X.
WordPerfect is a word processing application. At the height of its popularity in the late 1980s and early 1990s, it was the de facto standard word processor, but has since been eclipsed in sales by Microsoft Word. WordPerfect version 3.5e for Mac has been made freeware by Corel, and can be downloaded here http://main.system7today.com/software/wordperfect/wordperfect.html . It is a great, free alternative to Microsoft Word!
WP will run with OS 9 & below. If you run a version of OS X that can run in classic mode, you can use WP.
Using the free SheepShaver emulator, WordPerfect runs without problems (and very fast) on Intel Macs with all OS versions up to current (Mountain Lion at this writing). Recent additions by private supporters have given WP Mac probably the best outliner and regular expression search available on the Mac as well as a Microsoft Word converter and plugins for Spotlight and Quicklook.
