BMC ADO17 is the model code used by the British Motor Corporation (BMC) for a range of large family cars manufactured from September 1964 to 1975. The car was initially sold under the Austin marque as the Austin 1800, then by Morris as the Morris 1800, by Wolseley as the Wolseley 18/85, and later the Austin 2200, Morris 2200 and Wolseley Six. The 1800 was voted European Car of the Year for 1965.

The British Motor Corporation Limited (BMC) was a UK-based vehicle manufacturer, formed in early 1952 to give effect to an agreed merger of the Morris and Austin businesses.
