The name Balfour Declaration is applied to two key British government policy statements associated with Conservative statesman Arthur Balfour.

• The first Balfour Declaration, of 1917, was formally a private letter from the British politician Balfour to Lord Rothschild. It has been interpreted, especially by Israel, as committing Britain to favouring the establishment of a Jewish national home in Palestine.
• The second Balfour Declaration, of 1926, recognised the self-governing Dominions of the British Empire as fully autonomous states.
