General Sir Thomas Musgrave, 7th Baronet (1737–1812) was a British Army officer who served in the American Revolutionary War.

He entered the British Army in 1754 as ensign in the 3rd Buffs and quickly rose through the ranks to fulfil a distinguished career.

He commanded his regiment (40th foot) in the expedition to Philadelphia in the American War of Independence, where he greatly distinguished himself at Germantown, one of Earl Cornwallis's outposts in front of Philadelphia, when the American army in great force attacked the village on the morning of 4 October 1777.

Musgrave went in 1778 to the West Indies as quartermaster-general of the troops sent from New York under Major-general James Grant (1720-1806) of Ballindalloch, to capture and defend St. Lucia.

He left the West Indies sick, but afterwards returned as brigadier general to America, and was the last British commandant of New York.

Along with Brigadier General Samuel Birch, Musgrave signed the certificates of freedom for former black slaves after the war.

His hopes of a command against Tipu Sultan were disappointed by Lord Cornwallis, who appears to have thought that Musgrave did not work harmoniously with the civil government of Madras.

He died in London on 31 Dec. 1812, aged 75, and was buried in the churchyard of St George's, Hanover Square, in which parish he had long resided.
