HMS Reindeer (also Rein Deer) was a Royal Navy 18-gun Cruizer-class brig-sloop of the Royal Navy, built by Samuel & Daniel Brent at Rotherhithe and was launched in 1804. She was built of fir, which made for more rapid construction at the expense of durability. Reindeer fought in the Napoleonic Wars before succumbing in 1814 to the guns of USS Wasp during the War of 1812.
