Rush Sailing Club (RSC) is a community sailing club located in Rush, County Dublin, on the east coast of Ireland.

Founded in 1954 by a group of local enthusiasts who had few facilities and limited resources, the club's early members built their own boats and launched them directly off the beach.

Rush Harbour, near which the club is situated, lies on the north coast of County Dublin, just north of the rocky Rush Point.

The harbour offers anchorage off the village and includes a small drying boat pier where vessels that can take the ground may come alongside and dry out. The area is subject to tidal conditions referenced against Dublin (North Wall) with an offset of -01:00.
