Maxwell George O'Connell (born 4 April 1936 in Alberton, South Australia) was an Australian Test cricket match umpire.
In his first over as Test umpire he called "over" and turned to walk to square leg after John Snow bowled the last ball.
In its place a 'World Team' visited Australia and played a series of Test standard, although never officially recognised.
Dennis Lillee took 11 wickets, Rod Marsh finally achieved a century against England, debutant David Hookes hit English captain Tony Greig for five consecutive fours, Rick McCosker batted with a broken jaw, and Derek Randall scored a gallant 174, in a memorable match, attended by many of the past great names of Australian and English cricket.
Although never a first-class cricketer, O'Connell represented South Australia as a batsman at interstate Second XI standard.
