1,1,2-Trichloroethane, or 1,1,2-TCA, is an organochloride solvent with the molecular formula C₂H₃Cl₃ and the structural formula CH₂Cl—CHCl₂. It is a colourless, sweet-smelling liquid that does not dissolve in water, but is soluble in most organic solvents. It is an isomer of 1,1,1-trichloroethane, and a byproduct of its manufacture.

It is used as a solvent and as an intermediate in the synthesis of 1,1-dichloroethene.
