Jacques Marie François Bigot (14 October 1818 – 14 April 1893) was a French naturalist and entomologist most noted for his studies of Diptera.

Bigot was born in Paris, France, where he lived all his life, though he had a property in Quincy-sous-Sénart near Brumoy acquired in 1874, and where he died after an attack of influenza.

Bigot was a prolific author, describing more than 1,500 species of Diptera in more than 400 scientific publications and, like Francis Walker, his work was the subject of much later criticism.

R.A. Senior-White, in his 1927 eulogy of Enrico Brunetti, stated about Bigot “The death of Bigot in 1893 had put a term to the endless flow of description, insufficient and loosely worded, which Francis Walker and himself had been producing for forty years, whilst the chaos resulting therefrom had, in 1896, been ably summarized by van der Wulp in his classical ‘Catalogue of the described Diptera from South Asia’.”[2] Bigot's collection of more than 35,000 specimens of Diptera was purchased by George Henry Verrall in 1893 for 8,000 francs [3] and contains a wealth of type material of Diptera including those of Pierre-Justin-Marie Macquart, Ferdinand Kowarz, and Jean-Baptiste Robineau-Desvoidy.

When Verrall died, it passed to his nephew, dipterist James Edward Collin, who in 1961 gave part of it to the Natural History Museum in London and the Oxford University Museum of Natural History.
