Chiswick occupies a meander of the River Thames, 6 miles (9.7 km) west of Charing Cross.
The district is built up towards the north with more open space in the south, including the grounds of Chiswick House and Duke's Meadows.
Chiswick has one main shopping area, the Chiswick High Road, forming a long high street in the north.
 The river forms the southern boundary with Kew, including North Sheen, Mortlake and Barnes in the London Borough of Richmond upon Thames.
It includes the uninhabited island of Chiswick Eyot, joined to the mainland at low tide.
In the east Goldhawk Road and British Grove border Hammersmith in the London Borough of Hammersmith and Fulham.
In the north are Bedford Park and South Acton in the London Borough of Ealing, with a boundary partially delineated by the District line.
To the west, within Hounslow, are the districts of Gunnersbury and Brentford.
Chiswick is in the W4 postcode district of the London post town, which in a tribute to its ancient parish includes Bedford Park and South Acton, mostly within the London Borough of Ealing.

Bedford Park, designed largely by Norman Shaw, was described by Nikolaus Pevsner as the first place "where the relaxed, informal mood of a market town or village was adopted for a complete speculatively built suburb".
Some of the most beautiful period mansion blocks in Chiswick, such as Heathfield Court and Arlington Mansions, line the sides of Turnham Green – the site of the Battle of Turnham Green in 1642.
Other suburbs of Chiswick include Grove Park (south of the A4, close to Chiswick railway station) and Strand on the Green, a fishing hamlet until the late 18th century.
In 1896, Bedford Park was advertised as being in Chiswick, though at that time much of it was in Acton.
