Captain Jean-Marie Letellier (Brest, 3 October 1767 - Alexandria, 17 April 1830) was a French Navy officer.
[1] Letellier joined the Navy at age 13 as an apprentice, and was severely wounded after a few weeks of service when the escort on which he sailed battled two privateers.
Returned to Brest with the Illustre, Letellier sailed with the merchant navy until 1793, when he embarked on a privateer.
In September, he joined the Navy with the rank of ensign on the Pomone and served aboard until the action of 23 April 1794, in which the frigate was captured and Letellier was taken prisoner.
Released and returned to Brest, he was transferred to Toulon to serve on Conquérant and on Orient from January 1796.
