The Macartney Embassy; also called the Macartney Mission; was a British embassy to China in 1793. The Mission ran from 1792-94. It is named for the first envoy of Great Britain to China; George Macartney; who led the endeavour. The goal of the embassy was to convince Emperor Qianlong of China to ease restrictions on trade between Great Britain and China by allowing Great Britain to have a permanent embassy in Beijing; possession of 'a small unfortified island near Chusan for the residence of British traders; storage of goods; and outfitting of ships'; and reduced tariffs on traders in Guangzhou.

The embassy was ultimately not successful. This was not due to Macartney's refusal to kowtow in the presence of the Qianlong Emperor; as is commonly believed. It was also not a result of the Chinese reliance on tradition in dictating foreign policy but rather a result of competing world views which were uncomprehending and incompatible.
