 +//​ortho//​-CH<​sub>​2</​sub>​C<​sub>​3</​sub>​N was identified through three //a//-type transitions with //J// = 8 − 7 to 10 − 9 and //​K<​sub>​a</​sub>//​ = 0 in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope between 31.0 and 50.4 GHz. These transitions displayed partially resolved fine and hyperfine structure splitting; few components were blended by lines of other species. Also observed were four transitions of //​para//​-CH<​sub>​2</​sub>​C<​sub>​3</​sub>​N with //J// = 8 − 7 or 9 − 8 and //​K<​sub>​a</​sub>//​ = 1, which displayed well resolved fine structure splitting; some of these lines were also blended. A value of //​T//<​sub>​rot</​sub>​ = 7 ± 1 K was derived. The column density of CH<​sub>​2</​sub>​C<​sub>​3</​sub>​N is about a factor of ten lower than that of CH<​sub>​2</​sub>​CN. ​
