Prunus brigantina, called Briançon apricot (French: Abricotier de Briançon), Briançon plum (French: Prunier de Briançon), marmot plum (French: Marmottier), and Alpine apricot,[2] is a wild tree species native to France and Italy.

[3][4] Its fruit is edible and similar to the commercial apricot P. armeniaca,[5] but it is smooth unlike apricots.

[6] An edible oil produced from the seed, 'huile des marmottes', is used in France.

[5] It is disputed whether P. brigantina is an apricot or a plum.

It is grouped with plum species according to chloroplast DNA sequences,[7] but more closely related to apricot species according to nuclear DNA sequences.
