Little Warley is a village in the Brentwood district, in the county of Essex, England. It is situated south of Thorndon Country Park. The first outbreak of the 2001 United Kingdom foot-and-mouth outbreak occurred here.

Little Warley was an ancient parish. In 1931 it had a population of 395. On 1 April 1934 the parish was abolished and merged with Brentwood, except for a smaller part south of the railway which went to Little Burstead.

Since 2003 the area around St Peter's Church, but not the entire former parish, has formed part of the reconstituted civil parish of West Horndon.
