The Green Howards Regimental Museum is the museum of the Green Howards infantry regiment of the British Army. It is located in the old Trinity Church in the centre of the market place of Richmond in the Richmondshire district of North Yorkshire, England. The Green Howards were amalgamated with The Prince of Wales's Own Regiment of Yorkshire and The Duke of Wellington's Regiment, all Yorkshire-based regiments in the King's Division, to form The Yorkshire Regiment on 6 June 2006. Founded in 1938, The museum houses artefacts and displays showing three centuries of the history of the regiment.
