Merseyside Fire and Rescue Service is the statutory fire and rescue service covering the county of Merseyside in north-west England and is the statutory Fire and Rescue Authority responsible for all 999 fire brigade calls in Sefton, Knowsley, St. Helens, Liverpool and Wirral.

In 1974, six borough fire brigades (City of Liverpool, Birkenhead, Bootle, Southport, St Helens, and Wallasey), as well as parts of Lancashire County Fire Brigade and Cheshire County Fire Brigade merged to create Merseyside Fire Brigade.

Merseyside Fire Brigade became Merseyside Fire and Civil Defence Authority on 1 April 1986, as established by the Local Government Act 1985.

In an effort to modernise fire services nationally, the Fire and Rescue Services Act 2004 received royal assent on 22 July 2004. This legislation changed the name to Merseyside Fire and Rescue Authority. The change of name also reflects the fact that the service, in addition to fighting fire, conducts rescues such as road traffic collisions and is heavily involved in prevention work in communities.

Merseyside Fire and Rescue Authority headquarters is located on Bridle Road, Bootle

Since 2013, the MACC relocated from Derby Road, Kirkdale to a purpose built joint control centre with Merseyside Police, which is also located at the Bridle Road site.

Merseyside Fire and Rescue Authority is made up of five area commands as follows: Liverpool, Wirral, Sefton, Knowsley, and St Helens. Within these areas are:

Which provides Merseyside with 24-hour fire cover.
