Orsett Heath is a location and recently built hamlet in the unitary authority area of Thurrock, in the ceremonial county of Essex, England. It is located about twenty miles away from London.

At one time, Orsett Heath was probably part of a large swathe of heathland interspaced with woodland. This included Biggin Heath (heathland belonging to the manor of Biggin), Chadwell Heath (heathland belonging to the manor of Chadwell St Mary, not the place near Romford), Mucking Heath, Socketts Heath and Terrel's Heath all of which were on high ground compared to the nearby marsh and had poor sandy soil with underlying gravel and chalk.

It also lends its name to the nearby Orsett Heath Academy. Other schools nearby include Woodside Academy, The Gateway Academy and William Edwards School.
