Carillion plc was a British multinational facilities management and construction services company headquartered in Wolverhampton, United Kingdom. It is listed on the London Stock Exchange.

Carillion dramatically collapsed in January 2018 following multiple warnings about its financial situation.  It had public sector contracts in construction, tagging prisoners, building hospitals and schools, and providing school lunches.

It has dozens of subsidiary companies, a few of which are involved in NHS service provision. The most notorious is Clinicenta, who ran a hospital in Stevenage, and had their license revoked by the Care Quality Commission in 2013 after failing to provide a safe level of care to patients.
