I am going to revise his previous answer, because I do not agree. Although there have been some long bombs out of the park, the longest MEASURABLE home run was hit by Ted Williams on June 6, 1946.
A vivid reminder of the greatness Ted Williams bestowed upon the Red Sox franchise is the single red seat (location of where the ball landed) that stands out amongst its green counterparts in the right field bleachers.
On June 9, 1946, the Splendid Splinter connected off of Detroit's Fred Hutchinson for the longest home run ever hit into the Fenway bleachers.
56-year-old Joe Boucher, a construction engineer from Albany, New York, was in the seat when the ball, which traveled 502 feet, fell from the sky and deflected off his straw hat. But Boucher didn't end up with the ball, adding, "after it hit my head, I was no longer interested."
The seat, located in section 42, row 37, seat 21, was painted red to commemorate Williams' titanic blast, although at the time of the home run the bleachers were real bleachers and not individual seats.
All these years later, Red Sox fans, well aware of the seat's history, can be seen flocking to the area after each home game to have their picture taken in or around the seat.
While straight line measuring marks the spot at 502 feet, contemporary analysis by HitTracker has estimated the true distance of the home run to be between 520 and 535 feet, due to the elevation of the Fenway bleachers. No other player at Fenway Park has ever hit that seat since, although David Ortiz has come close.
Ronnie Green of the KC Royals hit the longest home run at Fenway Park in 1987
Faded Chair? There is a special red chair that is so colored because it is the confirmed longest home run ever hit at Fenway Park. It was hit by the famous Ted Williams.
