The Office for Environmental Protection (OEP) is a regulatory body for environmental protection in England and Northern Ireland^[1] "to provide independent oversight of the government's environmental progress". It was created as a statutory body by the Environment Act 2021.

The OEP was launched as an interim body in July 2021.^[2][3] The first chair is Glenys Stacey, who has called delays in the passage of the bill "extremely disappointing".^[4][5] Its first chief executive is Natalie Prosser and its headquarters are in Worcester. Concerns have been raised about potential lack of powers, independence, funding and about freedom of information. ^[6][3] The OEP is intended to replace the environmental protection functions of the EU, but a report by the Bingham Centre for the Rule of Law expressed concerns that the bill as of June 2021 would provide no equivalent legal remedy for breaches.^[7]The OEP was formally legally constituted on 17 November 2021,^[1] and was given an environmental governance role in England in January 2022,^[1] and in Northern Ireland in February 2022.^[8]
