Tarmac Group Limited was a multinational building materials company headquartered in Wolverhampton, United Kingdom. It produced road surfacing and heavy building materials including aggregates, concrete, cement and lime, as well as operating as a road construction and maintenance subcontractor.

The company was founded in 1903 by Edgar Purnell Hooley after he patented the road surfacing material tarmac in 1901. The company was formerly listed on the and was once a constituent of the FTSE 100 Index before being acquired by Anglo American in 1999.

In 2010, the group was separated into Tarmac Limited and Tarmac Building Products. Anglo American merged Tarmac Limited with the UK assets of Lafarge in 2013 to form a 50:50 joint venture, Lafarge Tarmac (now Tarmac Holdings). Tarmac Building Products was subsequently sold to Lafarge Tarmac in 2014.

The company was originally formed by Edgar Purnell Hooley as the Tar Macadam (Purnell Hooley's Patent) Syndicate Limited in 1903. The distinguishing feature of the new process was that it “tarred” cheap blast furnace slag, a steelworks by-product, rather than expensive roadstone and the Company entered into long term contracts with steelworks to ensure its supply.
