Caesium acetate or cesium acetate is an ionic caesium compound with the molecular formula CH3CO2Cs. It is often used in organic synthesis especially in Perkin synthesis: the formation of unsaturated cinnamic-type acids by the condensation of aromatic aldehydes with fatty acids.[2]

It may be formed by the reaction of caesium hydroxide or caesium carbonate with acetic acid. Caesium acetate is occasionally used instead of caesium formate in petroleum drilling fluids.
