The Austin Museum Partnership (AMP) is a 501(c)3 non-profit organization that promotes and facilitates collaboration within the museum community for the benefit of our museums and the community at large. Since 1998, the Austin Museum Partnership has coordinated Austin Museum Day, a community event which offers free admission and includes special programs and activities at museums and cultural institutions across the area. Austin Museum Day is held on the penultimate (second to last) Sunday of the month of September.
