Sundridge Park, also known simply as Sundridge, is an area of Greater London within the London Borough of Bromley and prior to 1965 it was in the historic county of Kent. It is situated north of Bromley, north-west of Widmore and Bickley, south of Grove Park and south-east of Downham. In the twentieth century Sundridge names began to overlap somewhat with neighbouring Plaistow, for example, the main Sundridge shopping parade by the station sits directly east of Plaistow Green, with business and facilities in the area using the two names interchangeably, and Plaistow Cemetery is actually on the Sundridge side of the border. However, during the early twenty first century there have been deliberate attempts to re-establish the separate identities of both villages, Sundridge has its own village sign, and representation has been made to the local council for a village sign for Plaistow. Plaistow refers especially to the area north of Sundridge Park station along Burnt Ash Lane, part of the A2212 road which runs north to south between Grove Park and Bromley.

Originally known as 'Sundresse', it is first mentioned in a charter of 987. In the middle ages the land was owned by the Le Blund family. In the early 1700s a large house was built on the site of Sundridge Park Manor; it was purchased and demolished by Sir Claude Scott in 1795, and the current building built in its place set in parkland.

Sundridge Park Manor is a Grade I listed mansion that was designed by John Nash and built by Samuel Wyatt. It has been used as a management and conference centre but is to be split into luxury apartments, a process that was underway as of March 2020. Much of the mansion's former grounds now forms Sundridge Park Golf Club.
