Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste. It is produced by fermentation of a sugar source, such as maize or beets, and then, by neutralizing the resulting lactic acid to create a compound having the formula NaC₃H₅O₃.

Sodium lactate, in the form of Ringer's lactate solution, is used as a medication, and is included on the World Health Organization's List of Essential Medicines.
