Odiham Castle (also known locally as King John's Castle) is a ruined castle situated near Odiham in Hampshire, United Kingdom.

It is one of only three fortresses built by King John during his reign. The site was possibly chosen by King John because he had visited the area in 1204 and it lay halfway between Windsor and Winchester.
