No there isn't. But it may be possible to use an Open Source license in 
conjunction with a closed license to achieve the same thing. It depends upon 
the nature of your software, and what you consider "commercial."

Trolltech licenses its Qt library under a dual QPL/GPL license. The only way 
you can use it for your own software is to make your stuff open source. If 
you want to release closed source software using Qt, you must purchase the 
professional license for quite a few dollars.

Commercial software is NOT the same thing as closed source. But 99% of it in 
the real world is. A scheme like Trolltech's may work for you if your 
software is used for the creation of other software.
