Adam Glen (1 March 1853 – 3 July 1937) was a New Zealand cricketer. He played six first-class matches for Otago between 1873 and 1887.^[1]

A right-arm medium-pace bowler who could bowl accurately for long periods, Glen was often able to extract unexpected bounce from the pitch.^[2] He achieved some impressive figures for Dunedin Cricket Club (such as 8 for 26, 6 for 9 and 9 for 18)^[3] and once took 101 wickets in a season at an average of 4.22.^[4] He was not as spectacularly successful at first-class level, but in his first match for Otago, who were weakened by the unavailability of several leading players, he was the team's best bowler against Canterbury, taking 4 for 55 in an innings defeat in February 1873.^[5] He was also effective against the touring Australians in 1877–78, taking 3 for 16 from 19.3 four-ball overs.^[6]

He later took up umpiring. His first first-class match as an umpire was the Otago–Canterbury match of February 1887 in Christchurch. The Otago player Charlie Frith failed to turn up on the first day, when Glen umpired; when Frith again failed to appear on the second day, Glen was prevailed upon by the Otago team to play – so Glen's debut as an umpire also became his last match as a player.^[7][8][9] He umpired 10 first-class matches between 1887 and 1898.^[10]

Glen married Frances Bellamy in Dunedin in March 1879.^[11] They moved in 1906 from Dunedin to Otautau, in Southland, where Glen worked in his son's softgoods business.^[12] They returned to Dunedin a few years later, where Glen worked among the composing staff at the Evening Star for 21 years until his retirement in 1934.^[13]

They moved to Hawera in 1935,^[14] and Glen died in Auckland in July 1937. His wife and a son and daughter survived him.^[15]
