Roger Maynwaring, variously spelt Mainwaring or Manwaring, (c. 1589/1590 – 29 June 1653) was a bishop in the Church of England, censured by Parliament in 1628 for sermons seen as undermining the law and constitution.

He returned to England in July 1642, shortly before the First English Civil War began, and, deprived of his See, retired to Brecon in Wales, where he died in June 1653.

Those who refused to pay were held without trial; when Chief Justice, Sir Randolph Crewe ruled it illegal, he was dismissed, and over 70 individuals jailed.

[3] Robert Sibthorpe, Isaac Bargrave and Matthew Wren also delivered sermons on the same lines, as part of a campaign co-ordinated by William Laud (then Bishop of Bath and Wells), which attempted to harness the Church of England to provide moral support for a fiscal policy.

[7] When Charles insisted, Maynwaring's superior, George Montaigne, Bishop of London, took the precaution of putting 'At the Royal Command' on the front page.

[b] Maynwaring was using theology to support policies most considered illegal, including Sir Edward Coke, a former Chief Justice, and most respected lawyer of the age.

[1] However, on 6 July he was pardoned by Charles, who gave him another parish, Stanford Rivers; thereafter he gained a series of promotions, becoming Dean of Worcester in 1634, then bishop of St Davids in 1636.
