- A38 is the reincarnation of an Ukrainian stone-carrier ship. With its inauguration on 30 April 2003, it started a new life on the Danube in Budapest, Hungary as a cultural venue. Since its opening it has become one of Budapest's most important venues, and according to artists' feedback, one of Europe's coolest clubs . The programming of the ship is very broad in terms of styles and genres but consistent in quality standards.
- The A38 is a major arterial route in Sydney, Australia. It runs from the M2 Hills Motorway in North Ryde to the Pittwater Road in Dee Why. It was formerly designated State Route 29 until mid 2013 when A38 replaced it as part of the statewide alpha numeric shield conversion.
A38 is a fermented dairy product, a Lactobacillus acidophilus yoghurt, made by Arla Foods. The product is sold in Denmark.
