Gepps Cross ( JEPS) is a suburb and major road intersection in the north of Adelaide, South Australia. Gepps Cross is traditionally seen as the end of the inner suburbs and the start of the outer northern suburbs, as it was home to a major abattoir (now closed and demolished) with holding yards and other open space. It is the first significant open space encountered after the North Parklands. It retains the open nature, even with warehouses, a velodrome, hockey stadium, Adelaide Raiders – a Croatian soccer club, and karate training facilities.

Gepps Cross is bounded on the south by the east–west road freight route of Grand Junction Road and is bisected east to west by the arterial Main North Road and Port Wakefield Road. Until 1995 the Northfield railway line which ran along the suburb’s northern boundary crossed Port Wakefield Road. The line further east crossing Main North Road had been closed in 1987.
