London Buses route 372 is a Transport for London contracted bus route in London, England. Running between Lakeside and Hornchurch, it is operated by Stagecoach London. The route is notable for being one a limited number of services run by Transport for London to cross the Greater London boundary.
Route 372 commenced operating on 9 November 2002 between Lakeside Shopping Centre and Hornchurch as a partial replacement for route 324, a route started by Capital Citybus, then being taken over by Ensignbus, but latterly with Town & Country Buses. Transport for London, had a brief spell of taking responsibility for cross-border routes, and route 372 was one beneficiary. However the sections of route 324 between Hornchurch and Romford and between Lakeside and Bluewater Shopping Centre were not replaced, with Ensignbus re-launching this link as route X80.
The route was initially operated by Arriva Southend operating from their Grays (GY) garage.
In January 2003, the route passed to Blue Triangle using four Plaxton Pointer 2 bodied Dennis Dart SLFs obtained from dealer stock.
On 27 March 2004, the route was retained by Blue Triangle.
An attempt to reroute the service through Hornchurch in 2008 led to opposition from locals.
The route's importance increased in November 2008 when Essex County Council supported route 55 was withdrawn, leaving many people with routes 372 and 370 as their only remaining routes.
On 26 March 2009, it passed to Thameside operating from their Rainham (RM) garage with new Alexander Dennis Enviro 200 Darts introduced.
