Joseph René Bellot was a French Arctic explorer who joined the expedition under the command of Captain William Kennedy in search of Sir John Franklin.

While making a perilous journey in the Wellington Channel in 1853, he disappeared in an opening between the broken masses of ice in the Wellington Channel.

A granite memorial obelisk designed by Philip Hardwick was unveiled in 1855 on the Thames riverside in front of Greenwich Hospital; a nearby Greenwich street, Bellot Street SE10, also carries his name.
