K Club, Golf resort in Straffan, Ireland

The K Club is a golf resort in Straffan featuring two courses designed by American architect Arnold Palmer, spread across parkland and meadow areas. The facility sits along the River Liffey in County Kildare and offers both traditional parkland conditions and links-style playing characteristics.

In 1831 Hugh Barton of the wine firm Barton and Guestier bought land at Straffan from the Henry family and had Straffan House built, completed in 1832 to a design based on a French chateau, probably by Frederick Darley. The estate stayed with the Bartons until 1949, when Derick Barton sold it to manufacturer John Ellis. After owners including film producer Kevin McClory, the Jefferson Smurfit Group bought the house in 1988 and opened the K Club three years later.

The Barton Restaurant earned a Michelin star in 1993 and 1994 under head chef Michel Flamme. The Palmer North Course hosted the Ryder Cup from 22 to 24 September 2006, the first time Ireland staged the event, and the Irish Open in 2016, won by Rory McIlroy.

Visitors need to arrange access in advance since this is a private membership facility with restricted entry outside of tournaments or guest arrangements. The best visiting season runs from May through October when weather conditions are most stable.

The Palmer North Course hosted the 2006 Ryder Cup, the first time the event was held in Ireland; it also staged the Smurfit European Open from 1995 to 2003 and again in 2005, and the 2016 Irish Open, won by Rory McIlroy. The South Course, also called the Smurfit Course, took the European Open in 2004, 2006 and 2007.
