The London Ambulance Service NHS Trust (LAS) is an NHS trust responsible for operating ambulances and answering and responding to urgent and emergency medical situations within the London region of England. The service responds to 999 phone calls across the region, and 111 phone calls from certain parts, providing triage and advice to enable an appropriate level of response.

It is one of the busiest ambulance services in the world, and the busiest in the United Kingdom, providing care to more than 8.6 million people, who live and work in London. The service is currently under the leadership of chief executive Daniel Elkeles and chair Andrew Trotter.^[2] The service employs around 5,300 staff.

It is one of ten ambulance services trusts in England providing emergency medical services, and is part of the National Health Service, receiving direct government funding for its role.

The LAS responded to over 2.1 million 999 calls for assistance, and over 1.2 million incidents in the year ended March 2020.^[4] Incidents rose by 20,000 in 2015/16, putting more pressure on the service. All 999 calls from the public are answered at one of the two Emergency Operations Centres (EOC) in Waterloo or Newham who then dispatch and allocate the appropriate resources. To assist, the service's command and control system is linked electronically with the equivalent system for London's Metropolitan Police. This means that police updates regarding specific jobs will be updated directly on the computer-aided dispatch (CAD) log, to be viewed by the EOC, and the resources allocated to the job.
