Horton Heath is a semi-rural village which forms part of the civil parish of Fair Oak and Horton Heath in the borough of Eastleigh in Hampshire, England.^[1][2][3] The village is about three miles southeast of Eastleigh town centre, and adjoins the village of Fair Oak.^[1]

The village greatly expanded during the late 1980s and 1990s, with developments such as The Drove and Meadowsweet way. A new village hall was also built at this time.

In 2014 a further development was proposed and permission was eventually granted for 2500 homes to be constructed on a 310 area situated to the south west of the original village. The development is meant to include a mix of housing, green spaces, commercial premises and sports and leisure facilities.

It forms part of the Southampton Urban Area.^{[citation needed]}

The current councillor is Michelle Marsh, who represents the Liberal Democrat party in the Fair Oak & Horton Heath ward.^[4] Marsh gained local notoriety for standing up against local felling.^[5]

The village has two pubs, 'The Brigadier Gerard' and 'The Lapstone'.
