Sir Alexander Paul Beresford (born 6 April 1946) is a British–New Zealander politician who served as the Conservative Member of Parliament (MP) for Mole Valley in Surrey from 1997 to 2024.

[8] Beresford was selected to fight the safe Conservative seat of Croydon Central following the retirement of former Cabinet minister John Moore.

When the number of seats in Croydon was reduced from four to three before the 1997 general election, Beresford failed to be selected for the newly drawn Croydon Central, and instead fought the safe Conservative Mole Valley seat in Surrey, where Kenneth Baker was retiring.

[16] Beresford, while serving as a backbencher, has been successful in utilising Private Members Bills and carefully chosen amendments to government legislation to achieve over ten legal changes which the BBC's Mark D'Arcy described as collectively having '...a significant impact'.

[19] At the snap 2017 general election Beresford was again re-elected with an increased vote share of 61.9% and a decreased majority of 24,137.

[22] In July 2022, during the political crisis caused by the Pincher Scandal, Beresford announced that he had lost confidence in Prime Minister Boris Johnson and felt he should resign.

[25] During the media coverage of the United Kingdom parliamentary expenses scandal, it was revealed that Beresford, who is a practising dentist, designated his west London property (which includes his dental surgery) as his second home, allowing him to claim allowances of three-quarters of the running costs of the property from the taxpayer.
