Alexander Stuart Douglas (1921–1998) was a physician and haematologist. He was Regius Professor of Medicine at Aberdeen University from 1970 to 1985.

He received international acclaim for his discoveries in relation to blood coagulation, causes of abnormal bleeding, and causes of thrombosis. He played a key role in identifying the role of anticoagulants and antiplatelet agents in preventing heart attacks, setting a modern benchmark for the treatment of heart disease.

He was one of the two people in 1951 establishing that Haemophilia split into two groups: isolating what is now commonly called Haemophilia B, then known as Christmas disease after its first known host, Stephen Christmas.
