Ángel Guastella (Buenos Aires, 7 November 1931 - San Miguel de Tucumán, 26 September 2016) was an Argentine rugby union footballer and coach.

[2] Guastella came to the Argentina national team along with Alberto Camardón, with both being assistants for the South African coach Izak van Heerden in 1964.

After the historical 1965 tour in South Africa, van Heerden remained in his home country and Guastella was named as his substitute in 1965.

In this last stage, Guastella decided to build a new team from scratch: first, naming Hugo Porta as captain, later, calling up the veteran Héctor Silva and young players such as Marcelo Campo, Alejandro Iachetti, Marcelo Loffreda, Rafael Madero, Tomás Petersen and Gabriel Travaglini.

Between 1985 and 1987, as assistant coach for Héctor Silva, the Argentina achieved its first victory against France, draw against New Zealand and was eliminated from the 1987 Rugby World Cup pool stage.
