Carl Joseph Fast

Carl Joseph Fast (; (also written as 法士) Foochow Romanized: Huák-sê̤u; October 8, 1822 – November 13, 1850) was the second Swedish missionary sent to China and the first Protestant missionary murdered in Fuzhou.

On January 1, 1850, Fast arrived in Foochow (today Fuzhou) as the missionary from the Lutheran Lund Missionary Society of Sweden, and was joined by later that year. The mission they set up in China was short-lived. On November 13, 1850, the two missionaries were brutally assaulted by Chinese pirates when they were coming up the River Min after getting money from a ship. Armed with a pistol Elgqvist survived the attack, but Fast was killed on the spot.

Fast was buried in Fuzhou Nantai.
