Merthyr's first reported match was an association football match played on 14/09/1876, when Merthyr lost 3-0 to Mr. Lloyd's School. The first public rugby game involving Merthyr was on 23 November 1876 against a side from Brecon. The result is believed to have been a draw. Merthyr RFC are recognised as one of the eleven clubs present on 12 April 1881 for the formation of the WelshRugby Union. The club, along with Brecon, Pontypool, Llandovery College, Lampeter College and Llandeilo then inaugurated the South Wales Cup competition in the 1877-78 season. During these early years Merthyr RFC played at the Plymouth Ground at Pentrebach and were known as Merthyr Alexandra. Around 1889 it seems Merthyr disbanded, mainly due to difficulty in being able to obtain a rugby ground. The club were "reorganised" in October 1889 and were now using the Penydarren Park. Following the First World War the Club played at Gwynnes Field, Cefn Coed and also at Penydarren Park although during the Second World War there was very little rugby played in Merthyr, a situation reflected throughout Wales. However, in 1948 a meeting governed by Cyril Williams, Monty Warrington and Ron Gethin was enthusiastically supported and the game of rugby union returned to Merthyr Tydfil. The club played out of Dix's field, Danydarren, and then on to Glyndyrus field Abercanaid, before moving to the current ground, the Wern in Ynysfach in 1958. In September 1960 the New Clubhouse opened in Ynysfach, and two years later, Merthyr Youth were formed.
Recent history
Merthyr RFC played Amateur District Rugby in the Rhondda and East Glamorgan District until they defeated Mold RFC at Abercynon to secure promotion and entry to the Fifth Division of the Heineken League under the Captaincy of Craig Dummett in 1993/4. Promotion immediately followed from the fifth to the fourth, then the third to the first in successive years. Merthyr remained in the First Division for six seasons before being relegated to Division 2 following a players' strike. It took three seasons to achieve promotion back to the first division. In 2013-14, the Ironmen completed a Double under the Captaincy of Steve Lang and coached by former Wales International Lee Jarvis. They won the LeagueDivision 1 East title, securing their promotion to the WRU Championship, and also won the SWALEC Plate Final 29-26, against Rhiwbina at the Millennium Stadium, Cardiff. In 2015-16, Merthyr RFC enjoyed further success by winning the WRU SWALEC Championship, gaining promotion to the WRU Principality Premiership. In 2016-17, the Ironmen completed a remarkable revolution by achieving their most successful season to date. The club won the WRU Principality Premiership during their inaugural season, with the final played against Aberavon RFC. They also reached the semi-final of the SWALEC Cup, eventually losing to RGC 1404.
