|}The Portland Handicap is a flat handicap horse race in Great Britain open to horses aged three years or older. It is run at Doncaster over a distance of 5 furlongs and 143 yards (1,137 metres), and it is scheduled to take place each year in September.
The event was established in 1855, and for a period it was known as the Portland Plate. The original course started opposite a coaching inn called Red House, and it featured a left-handed bend at about halfway. The race was later transferred to a straight course.
The Portland Handicap is held during Doncaster's four-day St. Leger Festival, and it is currently staged on the final day, the same day as the St Leger Stakes.
