Caesium carbonate is a white crystalline solid of formula Cs2CO3. It is more soluble in organic solvents than many other carbonates such as potassium carbonate, and therefore finds use as a base in organic chemistry.

Characteristic of carbonate salts, it reacts with protic acids to give carbon dioxide gas, water, and a caesium salt as follows:

Cs2CO3 + 2HCl → 2CsCl + H2O + CO2
