Titanium butoxide is a metal alkoxide with the formula Ti(OBu)₄ (Bu = –CH₂CH₂CH₂CH₃). It is a colorless odorless liquid although aged samples can appear yellowish. Owing to hydrolysis, samples have a weak alcohol-like odor. It is soluble in many organic solvents. Decomposition in water is not hazardous, and therefore titanium butoxide is often used as a liquid source of titanium dioxide, which allows deposition of TiO₂ coatings of various shapes and sizes down to the nanoscale.

Titanium butoxide is often used to prepare titanium oxide materials and catalysts.
