The Tithe Barn in Maidstone, Kent, is a large two-storey stone building on the east side of Mill Street. It was constructed in the 14th century as a tithe barn for the nearby Archbishop's Palace and was later used as the palace's stables. Construction is attributed to Archbishop Courtenay, who died in 1396. The barn is a Grade I listed building and a scheduled monument. It is home to the Tyrwhitt-Drake Museum of Carriages.
