The Yazghulami language (also Yazgulami, Yazgulyami, Iazgulem, Yazgulyam, Yazgulam, Yazgulyamskiy, Jazguljamskij, (Tajik: язғуломӣ (Yazghulomi)) is a member of the Southeastern subgroup of the Iranian languages, spoken by around 9,000 people along the Yazghulom River in Gorno-Badakhshan, Tajikistan.

The extinct Vanji language (also Vanži, Wanji) was once the nearest linguistic relative of Yazghulami.

The language was described in greater detail by French linguist Robert Gauthiot in Notes sur le yazgoulami, dialecte iranien des Confins du Pamir (1916).

The most significant research to date on the Yazghulami language was done by Russian linguist Dzhoi (Joy) I. Ėdel’man, resulting in multiple publications from the 1960s through the early 2000s.

The genitive 1 case marks attributive possession and is practically identical in function with the Tajik izofat =i which links a modifier to its noun.
