The Royal Oak is a Grade II-listed house (formerly a public house, or "pub") in Frindsbury, a Medway town in Kent, United Kingdom. The building dates from the late 17th century and it was used as a public house since before 1754. It is one of a few pre-Victorian buildings on Cooling Road in Frindsbury and one of the last remaining coach houses in the area. The two-storey timber-framed building was remodelled throughout the 18th and 19th centuries, with extensions in the 19th and 20th centuries, while the pre-1840 parts of the building remain intact to the present day.
