  Eleostearic acid is a fatty acid, one of two isomers of octadecatrienoic acid:
  
  * α-Eleostearic acid or (9Z,11E,13E)-9,11,13-octadecatrienoic acid, which occurs in tung oil and bitter gourd seed oil;
  * β-Eleostearic acid or (9E,11E,13E)-9,11,13-octadecatrienoic acid.
  
  The carboxylate (or conjugate base) of eleostearic acid is eleostearate. Esters of eleostearic acid are called eleostearates.
