Noncommercial or NC is one of the terms available in the Creative Commons license suite, present in the BY-NC, BY-NC-SA, and BY-NC-ND licenses.

The Defining Noncommercial study published in 2009 looks at how the online population understands "commercial" and "noncommercial" and contains some rules of thumb for licensors and licensees using or thinking about using licenses with the NC term.

As of late 2011, Creative Commons is working on version 4.0 of its license suite. Various options for addressing NC are under consideration. Please visit 4.0/NonCommercial.
