Ballybunion or Ballybunnion (Irish: Baile an Bhuinneánaigh) is a coastal town and seaside resort in County Kerry, Ireland, on the Wild Atlantic Way, 15 km (9 mi) from the town of Listowel. As of the 2022 census, Ballybunion had a population of 1,618.

The Placenames Database of Ireland associates the town's Irish language name, Baile an Bhuinneánaigh or the 'town(land) of An Buinneánach', with the Anglo-Norman surname "Bunyan". The Bunyan (Bonzon) family were historically associated with Ballybunion Castle.

Evidence of ancient settlement in the area includes promontory fort and ring fort sites in the townlands of Ballybunion and Doon West.

Ballybunion Castle was built in the early 16th century, on the site of an earlier promontory fort, by the (Geraldine) Fitzmaurice family. The castle was associated with the Bunyan family until the late 16th century, when William Óg Bunyan's lands were confiscated following the Desmond Rebellion. The castle has been a protected national monument since the 1920s.

A number of buildings within the town itself date to the 19th century, with the former Church of Ireland church (now a public library) and the Roman Catholic church dating to 1879 and 1897 respectively.

Ballybunion has two main beaches, divided by the Castle Green. The Ladies Beach is to the right and the Men's Beach to the left – names arising from the fact that both sexes previously swam on separate beaches. Further to the left of the Men's Beach lies the Long Strand, a 3.2 km stretch of sand, overlooked by the sand dunes of Ballybunion Golf Club.

In the summer, Ballybunion attracts tourists, and the beaches near Ballybunion are a common surfing site, with a dedicated surf school on the Men's Beach. Other traditions include seaweed baths, featuring sea water with serrated wrack. The town itself has a number of restaurants, pubs and cafes, and schools. A statue in the town commemorates a golfing visit, in 1998, by then US President Bill Clinton.

Ballybunion Golf Club was founded in 1893 and was previously ranked at number seven in Golf Digest's "100 Best Courses Outside the USA". There are 2 courses, the Old Course and the Cashen Course, both situated beside the beach. The club hosted the Murphy's Irish Open in 2000 and the Palmer Cup in 2004.

The local Gaelic football team, Beale GAA club, is named for a small townland a couple of miles up the coast from Ballybunion. Founded in 1972, the club's colours are green and red. It fields teams in competitions organised by the North Kerry Football Board.

The club's grounds, at Stack Park, are situated off Sandhill Road. This floodlight pitch provides training and matches for several divisions of players (incl under 8s, 10s, junior, and senior) as well as ladies football.

Ballybunion Health & Leisure Centre opened in 2007 and is situated on Kit Ahern Road.
