Simon IV, Count of Saarbrücken, Simon of Saarbrücken-Commercy (born before 1247; dead 1308). He was the Count of Saarbrücken (de) and Seigneur (lord) of Commercy (fr).

Biography
Simon was a son of Simon III? of Commercy (d.c. 1247) and grandson of Gaucher I (fr) (c.1185 - 1244/48), Seigneur of Broyes-Commercy, who was succeeded by Simon III's brother Gaucher II in Commercy, while Hugues, the elder brother of Gaucher I, had Broyes (fr) from their mother Agnès of Broyes (c.1175 - a. 1248). It is not clear if Simon III actually was a Seigneur of Commercy, but at least the title came to his descendants.

Simon's mother was Mathilde (c.1224 - 1276), Countess of Saarbrücken from 1270, daughter of Simon III (c. 1180–1243), Count of Saarbrücken with Lauretta of Upper Lorraine (1195 - a.1226). The County of Saarbrücken was given to the eldest sister Loretta (d.1270), with the others getting a share, but at her death the title went to Mathilde. As a widow Mathilde remarried in c.1248 to Amadeus (fr) (d. 1280), Seigneur (lord) of Montfaucon and had more children.

Simon's sister Laure (d. 1275), married Jean "the old" (1190–1267), Count of Chalon, Sire of Salins, regent of the County of Burgundy, and had several children, including Jean I of Châlon-Arlay.

Simon married twice and founded the House of Saarbrücken-Commercy (fr), having both fiefs as inheritance in 1274.
