Robert Arnold Lockyer Massie (born 14 April 1947) is a former Australian cricketer who played in six Test matches and three One Day Internationals (ODIs) in 1972 and 1973.

A swing bowler, he had a relatively short international career but is remembered for a Test debut in 1972 at Lord's where he took eight wickets in each innings, with figures of 16/137 for the match.

[2][3] The son of Arnold and Barbara Massie, Bob began playing cricket at age ten at the Bedford Park Youth Club, while a student at Hillcrest Primary School.

He moved on to Mount Lawley Senior High School and joined Bassendean-Bayswater in Western Australia's club competition.

When the touring England played Western Australia in the early stages of the 1970–71 season, Massie went wicketless and found his match opportunities restricted with Graham McKenzie back from international duty.

In the following match in Sydney, he took 7/76 in 21 overs including the scalp of Gary Sobers to secure his selection in the squad for the 1972 Ashes tour.

With Australia faltering at 8/101 in its second innings in the Third Test, with only a 75 run lead, Massie combined with John Watkins to add 83.
