The Massachusetts Handicap, frequently referred to as the "MassCap", was a flat thoroughbred horse race for three-year-olds and up held annually at Suffolk Downs in East Boston, Massachusetts, United States. It was an ungraded stakes race run over a distance of 9 furlongs on dirt. The race received Grade III status by the American Graded Stakes Committee for 2009, but the race was never held. The MassCap was stripped of its graded status in 2011 as a result of not being run for two consecutive years.
