Lambton is a York neighbourhood on the east bank of the Humber River, bounded by Black Creek to the north, Jane Street to the east and St. Mark's Road to the south. It grew from a mill settlement first known as Cooper's Mills, after the mills William Cooper ran on the Humber in the early 1800s, and later renamed Lambton Mills. Grist, saw and woollen mills operated along the river from 1850 to 1915.

The neighbourhood's landmark is Lambton House at 4066 Old Dundas Street. A hotel opened on the site in 1848, and the present brick building, attributed to William Tyrrell, dates from 1860. It served travellers on the main road west and operated as a hotel and tavern until 1988. The former City of York designated it in 1985, and today it is the only surviving building from the mill era, run as a museum by Heritage York. The Canadian Pacific Railway's Lambton Yard runs north of Dundas Street West through the neighbourhood. York became part of the amalgamated City of Toronto in 1998.

The Lambton tee is for the neighbours of the old mill village on the Humber's east bank.
