HMCS Cowichan (hull number MCB 162) was a Bay-class minesweeper that served in the Royal Canadian Navy during the Cold War.

Entering service in 1957, the minesweeper was used primarily as a training vessel on the Pacific coast of Canada.

The Bay class were designed and ordered as replacements for the Second World War-era minesweepers that the Royal Canadian Navy operated at the time.

[2][note 1] The Bay-class minesweepers were powered by two GM 12-cylinder diesel engines driving two shafts creating 2,400 brake horsepower (1,800 kW).
