Ammonium oxalate, C₂H₈N₂O₄ - more commonly written as (NH₄)₂C₂O₄ - is an oxalate salt with ammonium (sometimes as a monohydrate). It is a colorless salt under standard conditions and is odorless and non-volatile. It is a strong dicarboxylic acid and occurs in many plants and vegetables. It is produced in the body by metabolism of glyoxylic acid or ascorbic acid. It is not metabolized but excreted in the urine.^[1] It is a constituent of some types of kidney stone.^[2][3] It is also found in guano.

Ammonium oxalate is used as an analytical reagent and general reducing agent.^[1] It and other oxalates are used as anticoagulants, to preserve blood outside the body.
