Stella Maris (from the Latin for "star of the sea") was a ship involved in the Halifax Explosion in 1917. Stella Maris was built in Poplar, England in 1882 by Samuda Bios. The vessel was long, wide, and deep, and had a tonnage of 229. It was powered by steam. Formerly employed as an English gunboat and minesweeper, by 1917 it had been converted into a tugboat and purchased by Halifax Trading & Sealing Co, owned by James Augustus Farquhar.
