Suzanne Jovet-Ast (1914–2006) was a French botanist, who worked principally at the National Museum of Natural History, France.

In 1957, Suzanne Jovet-Ast was deputy director at the chair of Cryptogamy where she succeeded Robert Lami.

In 1975, she took over from Roger Heim as head of the Cryptogamy laboratory, becoming the first (and for a long time the only) female professor-administrator of the Museum, a position she held until her retirement.

[4] In her early work she studied the flowering plant family Annonaceae, while the majority of her professional career was focused on Bryophytes.

In the 1960s, Hélène Bischler and Jovet-Ast studied liverworts in the Mediterranean basin and arid and semi-arid zones in the field, which gave rise to numerous publications and applications in biochemistry and pharmacy.
