Charles-Mathias Simons (27 March 1802 – 5 October 1874)[1] was a Luxembourgish politician and jurist.

[1] From 1 August to 2 December 1848 he became Administrator-general of communal affairs in the de la Fontaine Ministry.

[1] After the Willmar government had been deposed by the governor Prince Henry, at the wish of William III, Charles-Mathias Simons was appointed prime minister on 23 September 1853.

This period also saw the opening of the first railway line in Luxembourg (4 October 1859) and the founding of the first banks, the Banque Internationale à Luxembourg and the Banque et Caisse d'Épargne de l'État.

Simons resigned on 26 September 1860, as opposition to his "coup d'état" government grew too strong in parliament after new elections.
