Peregrine Bertie was an English politician, the second son of Montagu Bertie, 2nd Earl of Lindsey. A member of the court party, later the Tories, he sat for Stamford from 1665 to 1679, and from 1685 to 1687. Most active in Parliament during the 1670s, he and other members of his family were consistent political supporters of Bertie's brother-in-law, the Duke of Leeds throughout several reigns. While he never achieved significant political stature, he did hold several minor government offices: he was a captain in the Royal Regiment of Horse Guards until 1679, and a commissioner of the Alienation Office and a customs officer. The death of his wife's brother brought the couple an estate in Waldershare, Kent, where Bertie ultimately settled. He sat for Westbury after the Glorious Revolution, but showed little political activity compared to others of his family. Bertie stood down from Parliament in 1695 and died in 1701, leaving two daughters.

Montagu Bertie, 2nd Earl of Lindsey, KG, PC, was an English soldier, courtier, and politician who sat in the House of Commons between 1624 and 1626.
