Bardwell Park is a suburb in southern Sydney, in the state of New South Wales, Australia. The suburb is located 12 kilometres south of the Sydney central business district and is part of the St George area. Bardwell Park is in the local government area of the Bayside Council. 

Bardwell Park was named after free settler Thomas Hill Bardwell who owned land in the area.  Bardwell Park is a leafy, predominantly residential area but features a small shopping centre around Hartill-Law Avenue and Slade Road, beside the Bardwell Park railway station.  The Bardwell Park - Earlwood RSL is also located beside the railway station and includes a new gym.

 Bardwell Park railway station is on the Airport & South Line of the Sydney Trains network.
There are good road links to the CBD along the Eastern Distributor, or avoid the roads entirely on a reasonably short train ride on the Eastern Suburbs and Illawarra Line, giving access to the CBD and Eastern Suburbs in the North, and Cronulla and the Illawarra region to the south. Proximity to the airport makes the area particularly popular with people who work there.

Bardwell Park borders an important piece of remnant bushland, the Wolli Creek Valley, beside Wolli Creek. The Wolli Creek Valley contains the only bushland of any size left in inner south-west Sydney. It is also the only large undeveloped natural space that remains in a heavily developed residential and industrial region. The park offers public transport access, family picnic areas, parkland, birdwatching, bushwalking, extensive views of sandstone escarpments, heathland and woodland forest
