In organic chemistry, an ethynyl group is a functional group with the formula −C≡CH. It is the acetylene molecule with one fewer hydrogen atom. Ethynyl group (HC≡C–), also designated as acetylenic group (from acetylene), and referred to in IUPAC chemical nomenclature as -yne suffix.

The ethynyl radical (systematically named λ 3-ethyne and hydridodicarbon(C—C)) is an organic compound with the chemical formula C≡CH (also written [CCH] or C 2 H). It is a simple molecule that does not occur naturally on Earth but is abundant in the interstellar medium.

Ethynyl is an organic radical and a terminal acetylenic compound. It derives from a hydride of an acetylene.
