HMCS Thunder (hull number MCB 153) was a Bay-class minesweeper that served in the Royal Canadian Navy for three and a half months in 1954 before being sold to the French Navy to become La Paimpolaise. The ship was named for Thunder Bay and was the second vessel to carry the name. Her name was given to her replacement, HMCS Thunder (MCB 161).
