Recusancy (from Latin: recusare, lit. 'to refuse') was the state of those who remained loyal to the Catholic Church and refused to attend Church of England services after the English Reformation.

The 1558 Recusancy Acts passed in the reign of Elizabeth I, and temporarily repealed in the Interregnum (1649–1660), remained on the statute books until 1888. They imposed punishments such as fines, property confiscation and imprisonment on recusants. The suspension under Oliver Cromwell was mainly intended to give relief to nonconforming Protestants rather than to Catholics, to whom some restrictions applied into the 1920s, through the Act of Settlement 1701, despite the 1828-1829 Catholic emancipation.

In some cases those adhering to Catholicism faced capital punishment, and some English and Welsh Catholics who were executed in the 16th and 17th centuries have been canonised by the Catholic Church as martyrs of the English Reformation.
