Yarwell is a village on the River Nene in the extreme east of the English county of Northamptonshire near the border with Cambridgeshire. Its name is derived from 'the spring where the yarrow grows'. At the time of the 2001 census, the parish's population was 316 people.
Yarwell has a pub called The Angel Inn, a village hall and a church. One of its two farms has been converted into a housing development and the other has applied for planning permission. Until recently there was a Methodist church in the village; the post office closed in 1993. The village school closed in the early 1960s and in 2003 was redeveloped into three houses. In total there are about 130 houses in Yarwell.
The preserved Nene Valley Railway has a station at Yarwell Junction. Before closure in the 1960s, this was the junction of two lines, one from Market Harborough and the other from Northampton. It is on the Cambridgeshire side of the Nene at .
