The P120C is a solid-fuel rocket motor designed for use as the first stage of the Vega-C and as the boosters of the Ariane 6 launch vehicles. The solid rocket motors were developed by Europropulsion, a joint venture of Avio and ArianeGroup, for the European Space Agency. The "C" in the name signifies its "Common" use across these vehicles.

As of July 2022, it holds the title of the world's largest and most-powerful single-piece solid-fuel rocket motor, surpassing its predecessor, the P80.^{[not verified in body]}
