Sir Samuel Thomas Evans GCB PC (4 May 1859 – 13 September 1918) was a Welsh barrister, judge and Liberal politician.

[1] Evans gained a large practice on the South Wales circuit and in 1901 he became the last QC appointed by Queen Victoria.

(He) first won his Parliamentary Spurs over the Church Discipline Bill, in which he showed a strength and sureness in debate which brought him out with credit even from contests with the great Gladstone himself.

But of late years he has been drawn off, like so many promising young Parliamentarians, to his work at the Bar, and the circuits have claimed much that was meant for the House of Commons.

[4] In October 1906 upon appointment as Recorder of Swansea, an office of profit under the Crown, he was required to seek re-election and in the by-election he was returned unopposed.

In March 1910 Evans decided to give up his political career and accept the post of President of the Probate, Divorce and Admiralty Division of the High Court of Justice.
