Margherita Rinaldi (12 January 1935 – 7 September 2023) was an Italian lyric soprano, primarily active in the 1960s and 1970s, after she made her debut as Donizetti's Lucia di Lammermoor in 1958, prompting her career at La Scala in Milan.

She performed at the Teatro Filarmonico of Verona as Amelia in Verdi's Simon Boccanegra in 1979, alongside Renato Bruson in the title role, directed by Filippo Crivelli [it] and conducted by Roberto Abbado.

[3] She sang at most of the major opera houses in Italy, in roles such as Amina in Bellini's La sonnambula, Donizetti's Adina in L'elisir d'amore and Norina in Don Pasquale, and Verdi's Gilda.

[4] She sang a wide variety of roles for RAI between 1963 and 1975, such as Bertha in Meyerbeer's Le Prophète, Handel's Cleopatra in Giulio Cesare and Ginevra in Ariodante, and Noraime in Cherubini's Les Abencérages.

[2] Angelo Sguerzi wrote for Stirpi canore about her "homogeneity of timbre, equality of registers, smooth and clear extension up to E-flat on the top, gentle, demure phrasing, without melodramaticism of dubious taste".

[3] Rinaldi made only two commercial opera recordings, as Gilda in Rigoletto opposite Rolando Panerai and Franco Bonisolli, which was also the soundtrack of a German television production, and as Ilia in Mozart's Idomeneo with Sir Colin Davis conducting.

[2] She performed the part of Maria Maddalena in Lorenzo Perosi's oratorio La Resurrezione di Cristo in 1969, and was the soprano soloist in both Handel's Messiah in 1970, conducted by Bertola, and in Beethoven's Ninth Symphony in 1981.
