Margam Cricket Club is one of the longest-standing cricket clubs in South Wales. It was officially founded in 1897 by workers from the estate of Lord Talbot which is now Margam Country Park but local historians believe that cricket was played on the estate some 25 years earlier.

The playing field was originally located on the grassy area alongside Margam Castle which has become, in recent years, a popular venue for concerts. At some time in the first quarter of the 20th Century, the pitch was moved to it's present location near the Orangery in the lower part of Margam Park. A new pavilion was built and is still used by Margam teams today.

Little historical information is available regarding the early Margam teams but the Club was involved only in friendly fixtures during the early 1970s. The club applied to enter the Morgannwg League in 1975 and progressed steadily through the divisions, winning the Premier Division title on two occasions in 1981 and 1983. In 1985, Margam entered the South Wales Cricket Association, widely recognised as the premier cricket league in Wales. Promotion from Division 5 was secured in 1987 and from Division 4 in 1988. The club's desire for success saw them employ their first overseas professional in 1991, a Guyanese batsman named Sunil "Tony" Dhaniram. Tony was followed into the Margam ranks in 1992 by countryman David Fingal, a fast bowler with fantastic stamina who also represented Guyana on two occasions. However, it was the arrival of batsman Awais Mahmood from Pakistan in 1993 which helped the club achieve promotion once more as, in 1993, Margam secured the Division 3 crown and with it the Glamorgan County Cricket Club Cup.

The decision of the South Wales Cricket Association to outlaw overseas players from 1994 onwards meant that Margam had to look closer to home for new players and in secured the services of former Surrey and Glamorgan seamer Mark Frost. However, 1994 was destined to be a season of disappointment for Margam as they were relegated from Division 2. The addition of Glamorgan 2nd XI batsman and wicket-keeper Jamie Bishop further strengthened the line up for the 1995 season and, sure enough, Margam captured their second Division 3 crown in three seasons. The departure of Mark Frost at the close of the 1995 season was seen by some as a major blow but it offered other players the chance to shine. Indeed, Margam competed more successfully in Division 2 during the 1996 and 1997 seasons with a number of young players making their mark. Sadly, a number of departures weakened the side and results proved more difficult to come by, culminating in a return to Division 3 at the end of the 1999 season and further disappointment in 2000 as the club was relegated for the second successive season.

The 2001 season was seen as one of consolidation and so it proved as the Club comfortably maintained their place in Division 4 but without really challenging for one of the promotion places. Several players performed well with both bat and ball and the return of a number of old faces strengthened the side but a lack of sufficient bowling firepower prevented the Club achieving any real success. In 2002, improved performances with both bat and ball, saw Margam just pipped to promotion on the last game of the season by Hills Plymouth and another third place finish in 2003 suggested that it could only be a matter of time before Margam once again begin the upward journey through the divisions.

Margam have had mixed fortunes since then, remaining in the fourth division for 2004 but achieving promotion into the third division in 2005. Unfortunately Margam were unable to build on this achievement and were relegated at the end of the 2006 season. 2007 saw Margam lose some players to other commitments and again they struggled with their league form. Margam fought for their place in the Fourth Division and it wasn’t until the very last game of the season that Margam new that their place in the Division was safe.
