In England and Wales, a magistrates' court is a lower court which hears matters relating to summary offences and some triable either-way matters. Some civil law issues are also decided here, notably family proceedings. In 2010, there were 320 magistrates' courts in England and Wales; by 2020, a decade later, 164 of those had closed. The jurisdiction of magistrates' courts and rules governing them are set out in the Magistrates' Courts Act 1980.

A summary offence or petty offence is a violation in some common law jurisdictions that can be proceeded against summarily, without the right to a jury trial and/or indictment.
