Patrick Clason (13 October 1789 – 30 July 1867) was a Scottish minister who served as Moderator of the General Assembly to the Free Church of Scotland in 1848/49.

He was born on 13 October 1789 in the manse at Dalziel near the River Clyde, the youngest son of Rev Robert Clason.

This temporary structure was later replaced in 1856 by a new Gothic-style church on West Crosscauseway at the junction with Chapel Street.

He was photographed in 1860 (illustrated below) at the foot of the steps to New College with several other ex-Moderators of the Free Church.

His brother the Rev James Clason (1783-1852) was also a Free Church minister.
