Prostaglandin G₂ (PGG₂) is an organic peroxide belonging to the family of prostaglandins. The compound has been isolated as a solid, although it is usually used in vivo. It quickly converts into prostaglandin H₂, a process catalyzed by the enzyme COX.

Prostaglandin G₂ is produced from the fatty acid arachidonic acid. The reaction, a double oxygenation, requires the enzyme cyclooxygenase, which inserts two molecules of O₂ into the C-H bonds of the substrate acid.
