CS13 was a collaborative arts space that existed in the Over-The-Rhine neighborhood of Cincinnati, OH. In 2009, a journalist, a social worker, a graphic designer, an accountant, a poet, an historian, and two artists founded CS13.

CS13 was founded as an art gallery and venue, however the diverse backgrounds and similar political ideologies and agendas of the gallery's founding members directed the bi-monthly art exhibitions towards often large and community oriented projects. The gallery-turned-collective collective regularly hosted art exhibitions, music shows, poetry, and a book club.

CS13 opened its doors in Fall 2009 and closed in Summer 2011.
