Admiral Charles Buckner (c. 1735[1]–1811) was a Royal Navy officer who became Commander-in-Chief, The Nore.

After his first wife's death, he married Anne Frewen, who was a great aunt of celebrated engineer Fleeming Jenkin, as recounted in Robert Louis Stevenson's Memoir of Fleeming Jenkin (1888).

Stevenson describes him as "that tall, rough-voiced, formidable uncle" who "was no enemy of dunces; he loved courage".

[2] In addition to his naval career, he was mayor of Chichester in 1784 and an alderman of the city afterward.

[6] The first round of negotiations, led by Buckner for the Navy, failed dismally with Buckner being threatened with a broadside attack from the third-rate HMS Inflexible which was being held by the mutineers.
