1,3-Diphenylurea is a phenyl urea-type compound with the formula (PhNH)₂CO (Ph = C₆H₅). It is a colorless solid that is prepared by transamidation of urea with aniline.

DPU is a cytokinin, a type of plant hormone that induces flower development. It occurs in coconut milk.[1] The cytokinin effect of DPU is relatively low, but other more potent phenylurea-type cytokinins have been reported.[2]
