The Protection from Harassment Act 1997 (c 40) is an Act of the Parliament of the United Kingdom. On introducing the Bill's second reading in the House of Lords, the Lord Chancellor, Lord Mackay of Clashfern, said, "The aim of this Bill is to protect the victims of harassment. It will protect all such victims whatever the source of the harassment—so-called stalking behaviour, racial harassment, or anti-social behaviour by neighbours." Home Office guidance on the Act says "The legislation was always intended to tackle stalking, but the offences were drafted to tackle any form of persistent conduct which causes another person alarm or distress."

Infield and Platford described the Act as "controversial".
