HMS Hindostan was a 56-gun fourth-rate ship of the line of the Royal Navy. She was originally the East Indiaman Hindostan, launched in 1789, that the Admiralty bought in 1795. She is known for two events, her voyage to China between 1792 and 1794 when she carried Lord Macartney on a special embassy to China, and her loss in a fire at sea in 1804.

The Macartney Embassy, also called the Macartney Mission, was the first British diplomatic mission to China, which took place in 1793. It is named for its leader, George Macartney, Great Britain's first envoy to China. The goals of the mission included the opening of new ports for British trade in China, the establishment of a permanent embassy in Beijing, the cession of a small island for British use along China's coast, and the relaxation of trade restrictions on British merchants in Guangzhou (Canton). Macartney's delegation met with the Qianlong Emperor, who rejected all of the British requests. Although the mission failed to achieve its official objectives, it was later noted for the extensive cultural, political, and geographical observations its participants recorded in China and brought back to Europe. It came to light in 1796 that a court official Heshen was stealing state funds and frustrated the mission.
