Orotidine is a nucleoside formed by attaching orotic acid to a ribose ring via a β-N1-glycosidic bond. It is found in bacteria, fungi and plants. It was first isolated in 1951 from the fungus Neurospora by A. Michael Michelson, William Drell, and Herschel K. Mitchell.[1] In humans, orotidine occurs as its 5'-phosphate (orotidylic acid), which is an intermediate in pyrimidine nucleotide biosynthesis (cytidine and uridine) that are found in nucleic acids. Orotidine itself is not a component of nucleic acid. Large amounts of orotidine are excreted in the urine of cancer patients treated with 6-azauridine.

The symbol commonly used for orotidine is O or Ord.
