Lam Qua (Chinese: 林官; Cantonese Yale: Lam Kwan; 1801–1860), or Kwan Kiu Cheong (關喬昌), was a Chinese painter from the Canton province in Qing dynasty China, who specialized in Western-style portraits intended largely for Western clients.
Lam Qua was the first Chinese portrait painter to be exhibited in the West.
He is known for his medical portraiture, and for his portraits of Western and Chinese merchants in Canton and Macau.
Parker commissioned Lam Qua to paint pre-operative portraits of patients who had large tumors or other major deformities.
Some of the paintings are now part of a collection of Lam Qua's work held by Yale University in the Peter Parker Collection at the Harvey Cushing/John Hay Whitney Medical Library; others are in the Gordon Museum, Guy's Hospital, London.
