Alexander Robert Charles Dallas (29 March 1791 – 12 December 1869) was an author, Church of England minister and Rector of Wonston in Hampshire from 1828 to 1869, a member of the family that descended from James Dallas of Rosshire in Scotland.

His grandfather, Dr. Robert Charles Dallas (1710–1769), was a doctor who amassed a fortune in Jamaica.

In the west of Ireland particularly Galway his evangelistic zeal and aggressive approach caused much conflict in the community.

Dallas' anti-catholic tirades caused much bitterness within the Irish Society, with the Dublin University branch opposing the alliance.

His attitudes and inspiration for his missions could have been due to his belief in Premillennialism or Millennialism, and the famine was a portent.

[7] At Morden, Surrey on 4 May 1818 Dallas married Mary Anne Ferguson, widow of James Edge, with whom he had two daughters and four sons.

There is a monument to his memory in St. Patrick’s Cathedral, Dublin and in a church in Clifden, Connemara in Ireland,[9] there is a commemoration regarding his efforts with the Irish Church Mission, with the inscription laboured prayerfully for the salvation of the perishing Roman Catholics of Ireland.
