Trimethylsilanol (TMS), also trimethylhydroxysilane, is an organosilicon chemical compound with the formula (CH₃)₃SiOH, or C₃H₁₀OSi. It is an organic derivate of silane substituted with three methyls and one hydroxyl group. It is a volatile organic liquid with boiling point between 98.6-99 °C.

TMS is used to apply hydrophobic coating on silicate surfaces. It reacts with the silicon atoms of the substrate, coating the surface with a layer of methyl groups. A commercial example is Magic Sand.

TMS is a common contaminant in spacecraft atmospheres, where it is present due to outgassing of silicone-based materials.

James "Spacecraft Maximum Allowable Concentrations for Selected Airborne Contaminants", Volume 1 (1994)] It is a potential end group hydrolysis product of polydimethylsiloxane chains.
