William Peartree (c. 1643–1714) was the 28th Mayor of New York City from 1703 to 1707. He married Anna, daughter of Daniel Litsco (1615–1662) (a lieutenant of Peter Stuyvesant) and Annetje Croesen Litsco, who later for many years entertained at "Mother Litsco's Tavern" on lower Pearl Street near the Brooklyn ferry. William Peartree's great-grandson, William Peartree Smith, was a founder of Princeton University.
