John Menzies Strain (8 December 1810 – 2 July 1883) was a Roman Catholic clergyman who served as the first Archbishop of the Metropolitan see of St. Andrews and Edinburgh, Scotland.

He left Rome on 3 August 1833, returning to Scotland, where he served at St Mary's, Edinburgh for two months, then appointed an assistant at Dumfries.

He was appointed to take charge of the mission at St Peter's Church in Dalbeattie on 17 March 1835, which included the greater part of Kirkcudbrightshire.

The Eastern District was elevated to the Archdiocese of St Andrews and Edinburgh, with John Menzies Strain appointed as its first archbishop.

[1][2] During his nineteen years' episcopate he saw the number of clergy and missions increase during his tenure; many new schools were opened, and several religious communities, both of men and women, introduced.
