Ravin de Sainte-Dévote (French pronunciation: [ʁavɛ̃ də sɛ̃t devɔt]; Monégasque: Valu̍n de Santa Devota, English: Ravine of Saint Devota) is a ward in the Principality of Monaco.

Since 2013, the area of the ward has become (together with Monaco-Ville) a reserved sector, "whose current character must be preserved".

At Monaco station (northwest) it borders France, and at the boulevard Albert 1st (south) it comes within around 40 metres of Port Hercules.

The ward borders Moneghetti in the southwest, La Condamine in the south and southeast, Monte-Carlo in the northeast, and the French commune of Beausoleil in the northwest.

For the purpose of the population statistics in the 2016 census, the Ravin de Sainte-Dévote ward was integrated into the quarter of Les Moneghetti.
