The simple answer is no, Leeds United has never won the Premier League, at least not yet. Of course, in 2020/21 the ‘Mighty Whites’ returned to the Premier League after a 16-year absence, but in their previous 12-year spell in the highest echelon of English football finished no higher than third place. They achieved that position in 1999/2000, under former assistant, and caretaker, manager David O’Leary, who was eventually appointed as permanent replacement for previous manager George Graham.
Of course, the Premier League did not start until 1992/93, when the 22 clubs in the First Division, as the top flight was previously known, broke away from the Football Association and the Football League. At that time, Leeds United was effectively defending champion of English football, having beaten Manchester United to the First Division title by four points in 1991/92. In fact, that title, under Howard Wilkinson, was Leeds’ third, following previous wins in 1968/69 and 1973/74, both under Don Revie. Indeed, following promotion from the Second Division in 1963/64, Don Revie’s Leeds finished no worse than fourth in the First Division for the next decade; Revie left Leeds in July, 1974 to succeed Sir Alf Ramsey as the manager of the England national team.
