Glamorgan County Cricket Club in 2023

The 2023 season was Glamorgan County Cricket Club's 136th year in existence and their 102nd as a first-class cricket county. They competed in the Second Division of the County Championship, as well as Group B of the One-Day Cup and the South Group of the T20 Blast. Just two of their fourteen County Championship matches produced results (one win and one loss), meaning they finished in fifth place in the eight-team division; meanwhile, they failed to capitalise on a good start in the T20 Blast, winning four of their first five matches before losing eight of their next nine to finish eighth out of the nine teams in the South Group. In the One-Day Cup, they failed to put together any consistent form; they won four of their eight matches, finishing in fourth place, three points behind Gloucestershire and Worcestershire in quarter-final places. Glamorgan played two 50-over matches at The Gnoll in Neath for the second year in a row, while also not returning to Penrhyn Avenue in Rhos-on-Sea for the fourth year in a row.

It was the team's fourth season with Matthew Maynard as their red-ball head coach and their second with David Lloyd as captain; both left at the end of the season, with Maynard stepping down and Lloyd moving to Derbyshire. Former Gloucestershire and England all-rounder Mark Alleyne joined the club as white-ball head coach, but his appointment as an assistant coach for the Welsh Fire in The Hundred meant Glamorgan turned to David Harrison to coach the side in the One-Day Cup. The team's overseas players were Australians Marnus Labuschagne and Michael Neser, and South African Colin Ingram; Australian Peter Hatzoglou and New Zealander Cam Fletcher also joined for the T20 Blast, while Australian Mitchell Swepson was brought in while Neser was on international duty with Australia for the 2023 Ashes series.

Pre-season and friendlies
Glamorgan's pre-season campaign took place in Zimbabwe, where they played a three-day match and a one-day match against Northerns, and three one-day matches against Southerns. On returning, they played a three-day game against Somerset at Taunton, before hosting Cardiff MCCU in another three-day match. They also played a one-day match against Herefordshire before the start of the One-Day Cup season, but it was rained off midway through the first innings.

20–23 April: Glamorgan v Durham
After a week off, Glamorgan returned to action at home to Durham buoyed by the return of their overseas players, Australians Michael Neser and Marnus Labuschagne.
