We report the first detection of the 36.4 GHz J = 4 → 3 rotational transition of interstellar cyanoacetylene (HC3N). The line was seen in emission from Sagittarius B2 and from the Mira variable, W Hydrae. The 18.2 GHz J = 2 → 1 line from Sgr B2 was reobserved to remove some confusion about the intensity of this line.
