The longest putt made in PGA Tour history is 111 feet, 5 inches long, and it was made by Craig Barlow at the 2008 edition of the now-defunct Buick Open in Michigan. Barlow made the putt in the final round at Warwick Hills Golf and Country Club on the first hole.
As far as Guinness World Records is concerned, their recognized longest putt ever made in PGA Tour history is a tie between Jack Nicklaus and Nick Price.
Jack Nicklaus made a 110-foot putt in the 1964 Tournament of Champions, played at the Desert Inn Country Club in Las Vegas, Nev. Nick Price also made a 110-foot putt in the 1992 PGA Championship at Bellerive Country Club just outside of St. Louis, Missouri. Both of those putts are recognized by Guinness World Records as the longest made in a "major golf tournament," which we interpret to mean as a professional golf tournament.
Those two putts aside, the PGA Tour has used ShotLink full-time since 2003 to track the length of every shot. The longest putts made in PGA Tour history since then start at 90 feet, going all the way up to Barlow's history-making putt.
