英国宇航海鹞（英语：British Aerospace Sea Harrier）是一种海军的垂直起降/ STOVL喷气式战斗机，兼并侦察和攻击机双重任务，是由霍克西德利鹞式飞机发展而来的。它首先开始服役于皇家海军是在1980年4月，名为FRS1海鹞，并得到了非正式的名称“莎尔”。在不寻常的时代作为海军和陆基空中优势战斗机，但且只拥有亚音速巡航能力的海鹞，作为这一重要角色肩负着皇家海军的航空母舰防空体系。

1982年英国和阿根廷对战的马尔维纳斯群岛战争（又名"福克兰群岛战争"）令海鹞一战成名。

The British Aerospace Sea Harrier is a naval short take-off and vertical landing/vertical take-off and landing jet fighter, reconnaissance and attack aircraft; the second member of the Harrier Jump Jet family developed. It first entered service with the Royal Navy in April 1980 as the Sea Harrier FRS1 and became informally known as the "Shar". Unusual in an era in which most naval and land-based air superiority fighters were large and supersonic, the principal role of the subsonic Sea Harrier was to provide air defence of Royal Navy aircraft carriers.
