Kyselina uhličitá (H2CO3) je veľmi slabá anorganická kyselina. Vzniká rozpúšťaním oxidu uhličitého vo vode. Niekedy sa pod kyselinou uhličitou nesprávne označuje aj celý takýto roztok. Čistá kyselina uhličitá v bežných podmienkach nie je známa.

V roztoku oxidu uhličitého vo vode je iba veľmi malé množstvo kyseliny uhličitej (aj to ionizovanej do prvého alebo druhého stupňa), väčšinu molekúl tvorí nezreagovaný oxid uhličitý, ktorý je s kyselinou uhličitou v chemickej rovnováhe:

CO2 + H2O ⇌ H2CO3
