Thomas Leeke Massie[1] (20 October 1802 – 20 July 1898) was an officer of the Royal Navy, who rose to the rank of admiral.

He was in HMS Martin at the demonstration against Algiers under Sir Harry Burrard Neale, and was frequently engaged in boat affairs with Greek pirates.

On 28 June 1838, Queen Victoria's coronation, he was made commander; and in 1839 was, with some others, sent out to Constantinople to assist in organising the Ottoman Navy.

They were, however, recalled after about six months; and in March 1840 Massie was appointed (as second captain) to HMS Thunderer with Maurice Frederick Fitzhardinge Berkeley.

In the Thunderer he took part in the operations on the coast of Syria in the summer and autumn of 1840, during the Oriental Crisis of 1840, culminating in the capture of Acre, for which he was promoted to be captain on 17 March 1841.
