Five ships of the Royal Navy have borne the name HMS Tigris, after the river Tigris, in modern-day Iraq. Another was planned but never completed:
HMS Tigris (1813) was a 36-gun fifth rate. She was built as HMS Forth but was renamed in 1812, before being launched in 1813. She was sold for breaking up in 1818.
HMS Tigris was to have been a 46-gun fifth rate. She was laid down in 1822 but was cancelled in 1832.
HMS Tigris (1829) was a 10-gun survey brig launched in 1829 and sold in 1862.
HMS Tigris (1834) was an iron paddle gunboat launched in sections in 1834. She was reassembled later that year at Basra, and was lost in 1835.
HMS Tigris (1882) was a paddle vessel launched in 1882 and sold into civilian service in 1904, being renamed Amarapoora.
HMS Tigris (N63) was a T-class submarine launched in 1939 and sunk by an unknown cause in 1943.
