    Yes you do. Snow Leopard will upgrade straight to ML. 


    OS X Mountain Lion system requirements

    To install Mountain Lion, you need one of these Macs:

    • iMac (Mid 2007 or newer)
    • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    • MacBook Pro (Mid/Late 2007 or newer)
    • MacBook Air (Late 2008 or newer)
    • Mac mini (Early 2009 or newer)
    • Mac Pro (Early 2008 or newer)
    • Xserve (Early 2009)


    Your Mac needs:

    • OS X v10.6.8 or OS X Lion already installed
    • 2 GB or more of memory
    • 8 GB or more of available space

    If you check the model number, you can tell which year it is. Apple menu/About This Mac/More Info/System Report:

    If the computer is compatible, it has been reported you can get Snow Leopard here:

    You should also check application compatibility since Mountain Lion does not support PowerPC applications.  Snow Leopard does support PowerPC applications.
