Fife ( FYFE, Scottish English: [fɐi̯f]; Scottish Gaelic: Fìobha, IPA: [fiːvə]; Scots: Fife) is a council area, historic county, registration county and lieutenancy area of Scotland. It is situated between the Firth of Tay and the Firth of Forth, with inland boundaries with Perth and Kinross (i.e. the historic counties of Perthshire and Kinross-shire) and Clackmannanshire. By custom it is widely held to have been one of the major Pictish kingdoms, known as Fib, and is still commonly known as the Kingdom of Fife within Scotland. A person from Fife is known as a Fifer. In older documents the county was very occasionally known by the anglicisation Fifeshire.

Fife is Scotland's third largest local authority area by population. It has a resident population of just under 367,000, over a third of whom live in the three principal settlements, Dunfermline, Kirkcaldy and Glenrothes.

The historic town of St Andrews is located on the northeast coast of Fife. It is well known for the University of St Andrews, the most ancient university of Scotland and one of the oldest universities in the world. From the 15th century it was the metropolis of the former Archdiocese of St Andrews, St Andrews Cathedral having been the seat of the most senior bishop of Scotland since the 10th century. St Andrews is also renowned as the home of golf.
