Sir Edward Hughes RN (c. 1720-1794) was an admiral of the British Royal Navy.

Hughes joined the Royal Navy in 1735, and four years later, was present at the capture of Portobelo, Panama. In 1740, he was promoted to lieutenant and served in the Cartagena expedition of 1741, and at the indecisive Battle of Toulon in 1744. In HMS Warwick, he participated in the action against the Glorioso, but without proper support from the Lark (which was sailing with the Warwick), the enemy escaped. The commander of the Lark was subsequently tried and condemned for his conduct, and Hughes received the vacated command. Captain Hughes was with Edward Boscawen at Louisburg and with Charles Saunders at Quebec.

He was in continual employment during the peace, and as commodore, commanded in the East Indies from 1773 to 1777.

It was not long before he returned to the East as a rear-admiral, with an overwhelming naval force. On his outward voyage, he took Goree from the French, and he was called upon to conduct only minor operations for the next two years, as the enemy could not muster any force fit to meet the powerful squadron Hughes had brought from the Channel.

In 1782, he stormed Trincomalee a few days before the squadron of Suffren arrived in the neighborhood. For the next year, these Indian waters were the scene of one of the most famous of naval campaigns. Suffren was perhaps the ablest naval commander that France ever produced, but his subordinates were factious and unskilful; Hughes on the other hand, whose ability was that born of long experience rather than genius, was well supported. No fewer than five fiercely contested general actions were fought by the two fleets, neither of them gaining a decisive advantage. In the end, Hughes held his ground.

After the peace, he returned to England, and, though further promotions came to him, he never again hoisted his flag. He had accumulated considerable wealth during his Indian service, which for the most part he spent in unostentatious charity. He died at his seat of Luxborough in Essex in 1794.
