The Mardyke is an area in Cork city, on the northern half of the long western part of the island formed by the two channels of the River Lee near the city centre. It was historically left as open space because the land along the north channel of the river is prone to flooding. From east to west these open spaces are: Presentation Brothers College, a boys' secondary school; the Mardyke ground of Cork County Cricket Club; Fitzgerald Park, which includes Cork Public Museum; Sunday's Well Lawn Tennis Club; and the athletic grounds of University College Cork.

Richard Beamish Cricket Grounds are a cricket ground in the Mardyke, Cork, Ireland. The cricket field and facilities are located on the southern bank of the River Lee, and overlooked by University College Cork and St Vincent's Catholic Church. The ground is officially named after Richard Beamish, but it is generally called The Mardyke after the area where it is situated, or the Cricket Club as it is the home ground of Cork County Cricket Club. The Munster representative provincial side, the Munster Reds, also use The Mardyke as their home ground.
