Deanne Bergsma (born 16 April 1941) is a South African ballerina, who made her career in the Royal Ballet at Covent Garden.

Apart from the stream of new works from Ashton and Macmillan the company's resident director-choreographers, it was the heyday of the partnership of Margot Fonteyn and Rudolf Nureyev.

A tall and elegant dancer Deanne Bergsma's earliest opportunities to shine were in the classical repertoire, notably as Odette/Odile in Swan Lake, as the Lilac Fairy in Sleeping Beauty and as Myrtha, Queen of the Wilis, in Giselle.

She had the benefit of personal coaching from Balanchine himself and from Bronislava Nijinska for the role of the Hostess in one of her best-known ballets, Les Biches.

A totally new dimension was added to Bergsma's repertory and reputation in 1970, when the American choreographer Glen Tetley chose her and Desmond Kelly to create the leading roles in his new ballet Field Figures.

At Covent Garden she also appeared in John Schlesinger's production of Offenbach's The Tales of Hoffmann in the non-singing role of Stella.

In Anthony Besch's production of Mozart's La Clemenza di Tito she made a mime appearance as Titus's inamorata Berenice.
