Hockley Woods is a large woodland in south-east Essex. It is a Local Nature Reserve, and parts are a Site of Special Scientific Interest. It is owned and managed by Rochford District Council.

Hockley Woods are the largest residual area of the wildwood, which covered much of Essex after the Ice Age, 10,000 years ago. Hockley Woods comprise several contiguous named woods including Great Bull Wood (30.2 ha), Great Hawkwell Wood (44.1 ha), Beeches or Beaches Wood (25.0 ha), Winks Wood (1.1 ha), Little Bull Wood (1.51 ha), Whitbred's Wood (3.57 ha) and Parson's Snipe (3.67 ha). Note that none of the woods is called Hockley wood. The woods extend over parts of the parishes of Hockley, Hawkwell and Rayleigh. The size of the woods is variously given as 130 hectares, 109 hectares and 91.3 hectares, although the latter is the SSSI only. Trees have recently (2022) been planted in the arable field to the south of Parson' s Snipe

The woods are on pre-glacial gravels and clay. The wooded areas are an intricate mosaic of various trees, every species developing under appropriate conditions. Oak and sweet chestnut develop on the higher ground, birch on the most acidic soils, hornbeam on the wet soils, willow and hazel along the streams. Other trees include pedunculate oak, sessile oak and birch. Ground flora include three species of orchid, and there is a stream and area of bog. Other species include the wild service tree, wood anemone, wood spurge and cow wheat that develop on the undisturbed soils of old woods. The protected heath fritillary butterfly is common on the site.

Hockley Woods are coppiced and used for timber. It is also the location for Hockley Woods parkrun, a free, weekly, timed 5km running event held every Saturday at 9 am.

Access to the wooded areas is unrestricted. There is a bus stop on Main Road (SS5 4RN) and a car park. The site has public toilets.
