Hippolyte-Jules Lefèbvre (4 February 1863 - November 1935) was a French sculptor and medallist who received numerous official marks of recognition in his day but is now largely forgotten.

His most prominent works are the monumental equestrian sculptures of Joan of Arc and Louis IX of France, set up on the Basilique du Sacré Cœur, Paris.

He began exhibiting regularly at the Salon des Artistes Français from 1887, and in 1892, after receiving seconds in 1888 and 1891, won the Grand Prix de Rome in sculpture; on his return to Paris he pursued a successful official career.

His kneeling funeral figure of Léon-Adolphe Cardinal Amette, 1923, is in the Chapel of Saint-Vincent-de-Paul, Notre-Dame de Paris.

[5] Lefebvre was often called upon to make commemorative medals, such as one celebrating the centenary of Argentine independence, 1910;[6] one commemorating Jules Gosset, for the Société des Sciences, Lille; one that the architect Louis M. Cordonnier, member of the Institut de France, distributed to friends and colleagues, 26 January 1912; Fondation Firmin Rainbeaux, 1930.
