A38 is an entertainment and cultural venue on the Danube river in Budapest, Hungary, opened on 30 April 2003. Its structure repurposes a decommissioned stone-carrier ship that operated in Ukraine and is now anchored permanently to the bottom of Petőfi Bridge. The venue variously encompasses a ruin bar, restaurant, exhibition hall, dancefloor, and concert hall.^[1]

The A38 is a member of the Trans Europe Halles organization.

The travel guide publisher Lonely Planet has voted A38 the "Best Bar in the World" in an online poll.^[1] Travel writer Craig Turp ranks it number one on his list of the top-10 clubs in Budapest, writing in Top 10 Budapest (2010): "Budapest's top dance venue is located on a ship moored on the Danube. There are three floors to choose from – the upper deck terrace for listening to the latest mellow sounds, the lower deck-level restaurant and the concert and dance hall below. A38 is also popular for classical and rock concerts, held in the hold."^[2]

According to the guide website Ruin Bars Budapest, the venue is "one of the best places for non-mainstream music lovers in Budapest with its rich concert programmes ... it outperforms itself by offering cool original and tribute concerts ... it is a community place ... a cultural venue offering a wide range of jazz, punk, world, electronic, contemporary, rock music along with various cultural events (film clubs, gastronomy events etc)".^[1]
