Machen is a large village 3 miles east of Caerphilly, south Wales, situated in the Caerphilly borough within the historic boundaries of Monmouthshire. It neighbours Bedwas and Trethomas, and forms a council ward in conjunction with those communities. It lies on the Rhymney River. Mynydd Machen (Machen Mountain) provides a view over the village. It is possible to walk up to and along the top of the mountain, where a number of large boulders are present.
Machen was a village rooted in the iron and coal industries stretching from the 17th Century. Though little trace remains, the village was the site of the Machen Forge and several coal mines. A local history trail visits some of these sites. Machen Forge was an early adopter of the Osmond process for the production of wrought iron.
Machen railway station, which closed in 1964, was an important junction on the Brecon and Merthyr Railway, with a branch to Caerphilly on the Pontypridd, Caerphilly and Newport Railway, closed to passengers in 1956.
Today a residual branch of the B&MR remains open to service the Hanson Aggregates quarry at Machen.
Alfred Edward Morgans (17 February 1850 – 10 August 1933), Premier of Western Australia for just 32 days in 1901, was born in Machen.
Ian Thomas (born 1979), former Glamorgan County Cricket Club cricketer, is from Machen. He played for Glamorgan between 1998 and 2005, winning two one day league winners trophies with the club. He is also known for having scored the first televised Twenty20 century in 2004 (116 Not Out against Somerset).
Men from Machen participate in one of the world's longest running epidemiology studies – The Caerphilly Heart Disease Study. Since 1979, a representative sample of adult males born between 1918 and 1938, living in Caerphilly and the surrounding villages of Abertridwr, Bedwas, Machen, Senghenydd and Trethomas, have participated in the study. A wide range of health and lifestyle data have been collected throughout the study and have been the basis of over 400 publications in the medical press. A notable report was on the reductions in vascular disease, diabetes, cognitive impairment and dementia attributable to a healthy lifestyle.

In 2008 Machen Remembered, the local archive group, received assistance from Community Archives Wales, to instruct their members in using computers to scan and upload their comprehensive Machen archive onto the Community Archives Wales website. This has been a great success with many of Machen's pictures now available for viewing on the website.
