The Museum of Old and New Art (MONA) is an art museum located within the Moorilla winery on the Berriedale peninsula in Hobart, Tasmania, Australia. It is the largest privately funded museum in Australia. The museum presents antiquities, modern and contemporary art from the David Walsh collection. Walsh has described the museum as a “subversive adult Disneyland.”

MONA was officially opened on 21 January 2011. Along with its frequently updated indoor collection, MONA also hosts the annual MOFO and Dark Mofo festivals which showcase large-scale public art and live performances.
