Leven is a seaside town in Fife, set in the east Central Lowlands of Scotland. It lies on the coast of the Firth of Forth at the mouth of the River Leven, 8.1 miles (13.0 km) north-east of the town of Kirkcaldy and 6.4 miles (10.3 km) east of Glenrothes.

Tourism is a major economic activity in and around Leven. There are several large caravan parks in and around the town, in addition to a number of hotels and guest houses. The neighbouring villages of Lundin Links and Lower Largo have over 50 high quality self-catering properties available for visitors.

The coast and the long sandy beaches are the main visitor draw. Leven has an attractive beach promenade with playparks and other facilities including an indoor Kids Action Zone. The promenade is part of the Fife Coastal Path that stretches for over 150 miles (240 km) from the Firth of Forth to the Firth of Tay. There are also popular family facilities and walks in the large parks at Letham Glen and Silverburn. The former includes a crafts centre and woodland walks, while the latter has attractive gardens and coastal views.

Golf is also a major draw with two courses at Scoonie and Leven Links and another within easy walking distance at Lundin Links. Leven Links has been used as a qualifying course for the Open Championship when it is held at St Andrews, the "home of golf" only 15 miles (24 km) to the north. There are also numerous bowls clubs in and around the town.

A heritage railway has also been established near the Burnmill industrial estate, alongside the now disused Leven-Thornton branch line. With trains running along the yard for half a mile, between April and October with a Santa special in mid-December. The Fife Heritage Railway is the first of its kind in Fife since the closure of Lochty Private Railway in 1992. The railway completed its first steam engine in August 2016.

Levenmouth Leisure Centre, at the start of the promenade, is an all-weather attraction with a large, modern indoor swimming pool and sports facilities. History enthusiasts can find out about the area's past at the Heritage Centre in neighbouring Methil, only a 15-minute walk from Leven town centre.

The town centre is the main shopping centre for a wide area with a number of national chain supermarkets and retailers as well as award-winning independent local retailers. It also has a large number of restaurants and cafes.
