Mavis Lilian Batey, MBE (née Lever; 5 May 1921 – 12 November 2013), was a British code-breaker during World War II. She was one of the leading female codebreakers at Bletchley Park.

She later became a historian of gardening, who campaigned to save historic parks and gardens, and an author. Batey was awarded the Veitch Memorial Medal in 1985, and made a Member of the Order of the British Empire (MBE) in 1987, in both cases for her work on the conservation of gardens.
