英国海外航空公司（英语：The British Overseas Airways Corporation，简称BOAC）是一家英国的航空公司，由帝国航空公司（Imperial Airways）和前英国航空有限公司（British Airways Ltd）合并而成。在1939年至1946年间，英国海外航空公司是英国的国营航空公司，经营国内及国际航线服务。1946年起，英国海外航空公司则变成只负责长程航线的国营航空公司。根据1971年通过的英国国会法，英国海外航空公司在1974年与英国欧洲航空公司（British European Airways）正式合并成为现时的英国航空公司（British Airways）。

British Overseas Airways Corporation (BOAC) was the British state-owned airline created in 1940 by the merger of Imperial Airways and British Airways Ltd. It continued operating overseas services throughout World War II. After the passing of the Civil Aviation Act of 1946, European and South American services passed to two further state-owned airlines, British European Airways (BEA) and British South American Airways (BSAA). BOAC absorbed BSAA in 1949, but BEA continued to operate British domestic and European routes for the next quarter century. A 1971 Act of Parliament merged BOAC and BEA with effect from 31 March 1974, forming today's British Airways.
