Khulsanurus (meaning "tail from Khulsan") is an extinct genus of alvarezsaurid theropod dinosaur from the Late Cretaceous Barungoyot Formation of the Khulsan Locality in the Gobi Desert region of Mongolia.

[1] Averianov & Lopatin (2021) placed Khulsanurus in a polytomy with Albinykus, Ceratonykus, Linhenykus, Parvicursor, Xixianykus, Qiupanykus, Nemegtonykus, PIN 5838/1 (=Ondogurvel) and a clade containing Shuvuuia and Mononykus in a strict consensus tree using unweighted characters.

However, Averianov & Lopatin (2021) also recovered it in a polytomy with only Albinykus, Xixianykus, PIN 5838/1 (=Ondogurvel), Mononykus and Shuvuuia in a consensus tree using implied weighting.

[1] Averianov & Sues (2022) conducted a phylogenetic analysis using implied weighting which recovered it in a similar position but with inclusion of a clade containing Linhenykus, Ceratonykus and Parvicuror and the exclusion of Qiupanykus and Nemegtonykus, while a 50% majority rule tree from the same analysis placed it within a polytomy with two clades.
