An organic base is an organic compound which acts as a base. Organic bases are usually, but not always, proton acceptors. They usually contain nitrogen atoms, which can easily be protonated. For example, amines or nitrogen-containing heterocyclic compounds have a lone pair of electrons on the nitrogen atom and can thus act as proton acceptors. Examples include:

• pyridine
• alkylamines, such as methylamine
• imidazole
• benzimidazole
• histidine
• guanidine
• phosphazene bases
• hydroxides of quaternary ammonium cations or some other organic cations
