Trimethylsilanol (TMS) is an organosilicon compound with the formula (CH3)3SiOH, which is a volatile organic liquid with a boiling point of 98 °C. The heat of evaporation is 45.64 kJ·mol−1, the evaporation entropy 123 J·K−1·mol−1.  Trimethylsilanol is a weak acid with a pKa value of 11. The acidity is comparable to that of orthosilicic acid, but much higher than the one of alcohols like tert-butanol (pKa 19).

Trimethylsilanol can not be produced by simple hydrolysis of chlorotrimethylsilane, as this reaction leads to the etherification product hexamethyldisiloxane, because of the by-product hydrochloric acid.

Trimethylsilanol is accessible by weakly basic hydrolysis, since the dimerization can thus be avoided. Trimethylsilanol can also be obtained by the basic hydrolysis of hexamethyldisiloxane.

Trimethylsilanol is being tested for use as an antimicrobial agent, and also used for hydrophobic coating on silicate surfaces. It reacts with the silanol groups (R3SiOH) of the substrate, resulting in a layer of methyl groups.
