Bermuda II was a bilateral air transport agreement between the governments of the United Kingdom and the United States signed on 23 July 1977 as a renegotiation of the original 1946 Bermuda air services agreement. A new "open skies" agreement was signed by the United States and the European Union (EU) (of which the United Kingdom is part) on 30 April 2007 and came into effect on 30 March 2008, thus replacing Bermuda II.
