Lithium monoxide anion (LiO) is a superbase existing in the gas phase. It was the strongest known base until 2008, when the isomeric diethynylbenzene dianions were determined to have a higher proton affinity. The methanide ion CH3 was the strongest known base before lithium monoxide anion was discovered.

LiO has a proton affinity of ~1782 kJ/mol.
