Raith (Scottish Gaelic: rath, "fort" or "fortified residence") as an area once stretched from the lands of Little Raith (earlier Wester Raith), south of Loch Gelly, as far as Kirkcaldy and the Battle of Raith is said to have been fought here in 596 AD. Raith Hill, west of Auchtertool and immediately to the east of the Mossmorran fractionation plant, may also be in reference to this wider area or may refer to an actual fort on this hill, distinct to the one naming the area.
The name is found in Kirkcaldy's professional football team, Raith Rovers. This name was earlier borne by an entirely distinct team, probably named for the Little Raith colliery, east of Cowdenbeath, which merged with Cowdenbeath Rangers to form Cowdenbeath F. C..
Raith House and Raith Tower sit on Cormie Hill to the west of Kirkcaldy and several parts of the town are built on land formerly of the Raith Estate. The modern housing estate bearing the Raith name dates from long after the origins of the football team.
