The Magistrates' Association is the membership organisation for magistrates in England and Wales. By virtue of its education and training functions it is a charitable organisation and is funded by its members to promote the magistracy.

The idea of forming an association of magistrates came from a Derby magistrate, Alderman Wilkins, in 1920. The inaugural meeting of the association was held at Central Hall, Westminster, on 28 October 1921. Lord Haldane was elected the association's first president. Thereafter the Lord Chancellor of the day was president, but when the role of the Lord Chancellor changed with the passing of the Constitutional Reform Act 2005 the Lord Chief Justice took on the role.

By 1945, membership had grown to 5,288 members, and it had 16,354 at its fiftieth Anniversary in 1970. Today, it represents over 80% of active magistrates.

It received a royal charter in October 1962.

The association was established to:

Since 1969, it has helped to develop various sentencing guidelines. It also organises conferences and publishes a magazine, Magistrate. Members also participate in local branch activities.

The governing body is the Board of Trustees. A Council advises the Board. Various standing committees are populated by association members and focus on specific areas of magistrates' activities.

The current chair is David Ford JP.
