Tetrabutyltin is the organotin compound with the molecular formula Sn(CH₂CH₂CH₂CH₃)₄ or SnBu₄, where Bu is butyl −CH₂CH₂CH₂CH₃. Sometimes abbreviated TTBT, it is a colorless, lipophilic oil.^[3]

Tetrabutyltin is a precursor to tributyltin and dibutyltin compounds. By the redistribution reaction with tin(IV) chloride it forms tributyltin chloride and dibutyltin chloride. These compounds are starting materials for a wide range of organotin compounds used as stabilizers for PVC and as biocides, fungicides, wood preservatives, and (historically) marine anti-biofouling agents.^[4]
