Simon II of Clermont-Nesle (c. 1210 - 1285/86) was Seigneur (Lord) of Ailly, Maulette and Nesle (in Picardy) . Note that there is a great confusion of names and titles within this family and with people with the same or similar names, as with many other medieval lords because of contradictory and incomplete documents.

Simon was the eldest son Raoul I of Clermont-Nesle (c. 1185 - c. 1226), Seigneur of Ailly, Maulette, and perhaps Nesle jure uxoris and the Constable of France, who was son of Simon I, Seigneur of Ailly-sur-Noye , younger brother of Raoul I the Red, Count of Clermont, married to Alix, daughter of Valeran III. Simon's mother was Gertrude of Nesle (1175 - 1239), daughter of Jean of Nesle, Châtelain of Bruges (d. 1197/1200), sister of Jean II, Seigneur of Nesle (d. 1239), who testamented Nesle to Raoul and his heirs, lacking own issue. Simon had several siblings, a brother Raoul (d.a. 1243), lord of Tartigny, sometimes numbered II, and hence a possible ancestor to some of the children, especially those attributed to Simon's son Raoul, when one regards the Seigneurie of Tartigny.

Simon was a counsellor of King "Saint" Louis IX of France, especially in areas of justice. Jointly with Matthieu of Vendôme he was the regent of the kingdom 1270-71 when Louis and his son Philip were away on the Seventh Crusade, using the title "lieutenant" (i.e. "having the place"). In the process of canonisation of king Louis in 1283 he was one of those bearing witness.

Simon was also a tutor of the Enfants de France, the children of the king, appointed by Philip III.
