Edward Montagu, 1st Earl of Sandwich (1626–1672) was an English naval officer. He served the Commonwealth of England as General at Sea, and after the Restoration he served Charles II as Admiral, commanding the fleet that brought him back from exile.

In the Second Anglo-Dutch War he fought at the Battle of Lowestoft but defeat at the Battle of Bergen led to him being removed from service.

In the Third Anglo-Dutch War he was Vice-Admiral of the Blue at the Battle of Solebay, where his flagship, the Royal James was attacked by fire ships and burned. He drowned trying to escape.

Montagu was a distant relation of Samuel Pepys who started his career as a minor member of Montagu's household and benefitted from his various acts of patronage.
