John Thomas Becher (born 1770 died 1848), was an English clergyman, social reformer and Vicar-General of Southwell Minster from 1818 to 1840.

He appears to have moved to Southwell by 1792, and after ordination in the Church of England he became Perpetual curate of Thurgarton and Hoveringham, Nottinghamshire in 1799.

He took a warm interest in everything connected with the social condition of the people, and, whether he was its founder or not, zealously promoted the establishment of a friendly society at Southwell.

In 1826 appeared his Observations upon the Report from the Select Committee of the House of Commons on the Laws respecting Friendly Societies, exemplifying and vindicating the principles of Life Assurance adopted in calculating the Southwell Tables, together with the heads of a Bill for improving the constitution and management of such institutions.

The select committee of the House of Commons on agriculture in its report pointed attention to the value of Becher's system, which was also favourably mentioned by the Quarterly Review.

In 1837, he apparently converted, on at least one point, Finlaison, his former antagonist, and there appeared Rules of the Northampton Equitable Friendly Institution, and tables calculated from actual returns of sickness, old age, and death, by the Rev.

In 1818 he became a prebendary of Southwell, and was vicar-general of the collegiate church, the dean and chapter of which presented him in 1830 to the rectory of Barnborough, Yorkshire.
