The Hogsmill's source is a chalk spring at or near grid reference TQ219627 in Ewell in Surrey. It flows in a northerly direction through Old Malden, New Malden and Berrylands to the River Thames close to the centre of Kingston upon Thames at grid reference TQ177691. The river is 6 miles (9.9 km) in length and has a catchment area (water basin) of 73 km².
The main river flows through much low-lying land, the majority of which is given over to sports grounds, until the final section through the built-up area of Kingston. Epsom and Ewell borough council maintain the Hogsmill Open Space which follows the river until the boundary with Kingston.

The Hogsmill has appeared in the art of John Millais in his rendition of Ophelia, and of William Holman Hunt who painted The Hireling Shepherd on the meadows by the Hogsmill, looking north towards Ewell Court Farm. The doorway (to the soul) in Hunt's The Light of the World is believed to be part of a gunpowder mill on the Hogsmill at Ewell.
