Letterkenny Golf Club (often referred to as the Barnhill) is a golf club located on the banks of Lough Swilly in Letterkenny, County Donegal, Ireland. The club was founded in 1913.

Golf began in the town many years before 1913 on rough ground near the Ramelton Road. Golfing facilities later moved to a 47-acre (190,000 m²) 9-hole course at Crievesmith, in Oldtown, in 1913 where the club was formed. Crievesmith was sold in 1965 for £3000 and the club moved to Barnhill and remain there to this day. The ground at Crievesmith is currently^[when?] used for housing.^{[citation needed]}

When the club moved to Barnhill an old farmhouse located on the land was used as the clubhouse. This farmhouse was extended in 1967 before new 10,000 sq ft (930 m²) clubhouse was opened in 1999 with a restaurant and conference facilities. In July 2007, the Declan Brannigan redesigned course was officially opened, addressing drainage problems which the old course had suffered from.^{[citation needed]} The course has 18 holes and has views of Lough Swilly.

In 1999, the club hosted the Ladies Irish Open.^[1][2]
