Howth Yacht Club, situated on the Middle Pier in Howth Harbour on Ireland's east coast, is one of Ireland's premier sailing clubs, originally founded as Howth Sailing Club in 1895.

It operates a 250-berth marina that welcomes visitors and is well sheltered, accessible at any state of tide, and ideally positioned for north- and southbound traffic on the Irish Sea.

The club maintains a listening watch on VHF Ch 37 (M1) and Ch 80 during marina office hours. Its expansive clubhouse — among the largest of any sailing club in Ireland and the UK — overlooks the marina.

The club runs active keelboat and dinghy racing fleets and regularly hosts national and international sailing championships.

With strong road and rail connections to Dublin city centre and proximity to Dublin Airport, it serves as a practical base for crew changeovers and cruising the wider Irish Sea.
