Markham is a small village in the South Wales Valleys in Caerphilly County Borough, to the northeast of Bargoed. Built as a planned garden village, it grew out of the need to house employees of Markham Colliery. Today it is a district of the community of Argoed. The B4511 road links to Markham from Aberbargoed and joins the A4048 road to the north of Argoed. The Sirhowy River flows to the east of the village.
At the heart of the village is an active Methodist congregational chapel. It celebrated its centenary in 2013. A Welfare Hall was built during its time as a mining village, which also housed a cinema. Today the hall is still used as a Social Club.
The village's primary school, Markham Primary School, is a feeder school for Pontllanfraith Comprehensive School and Blackwood Comprehensive School. Markham RFC currently play in the WRU Swalec League Five South East. Markham RFC have won the Cyrus Davies Cup three times. They have also been semi-finalists of the Worthington District's Cup three times.
