Triethylsilane is the organosilicon compound with the formula (C₂H₅)₃SiH. It is a trialkylsilane. The Si-H bond is reactive.

It was first discovered by Albert Ladenburg in 1872 among the products of reduction of tetraethyl orthosilicate with sodium and diethylzinc. He also prepared it by a stepwise reduction via ethoxytriethylsilane and named it silicoheptyl hydride, reflecting the idea of a silicon compound analogous to a seven-carbon hydrocarbon.

This colorless liquid is used in organic synthesis as a reducing agent and as a precursor to silyl ethers. As one of the simplest trialkylsilanes that is a liquid at room temperature, triethylsilane is often used in studies of hydrosilylation catalysis.
