Maria Antonelli (1903–1969) was an Italian fashion designer.

In July 1951, together with other designers such as Vincenzo Ferdinandi, Roberto Capucci, the Atelier Carosa, Giovannelli-Sciarra, Polinober, Germana Marucelli and Jole Veneziani, she took part in the show organised by Giovanni Battista Giorgini in Florence that attempted to establish Italian fashion as a rival to France.

[3] She dressed the actresses Clara Calamai, Anna Magnani, and Alida Valli.

In 1969, she took part in the Mare Moda festival, where her models were described by Antony King-Deacon of The Times as "thrashing about with their arms and legs in a sort of frenzied apathy.

Her designs featured in the Victoria & Albert Museum's exhibition The Glamour of Italian Fashion 1945-2014 in 2014.
