Parnassius tianschanicus, the large keeled Apollo, is a high-altitude butterfly. It is a member of the snow Apollo genus (Parnassius) of the swallowtail family, Papilionidae.

It is found in Uzbekistan, Tajikistan and Kyrgyzstan. Afghanistan, Pakistan, south-western China and Xinjiang, reported from northern India (Jammu and Kashmir) by some authors by mistake.

Locally very common but generally a rare butterfly. It is declining due to changes in its habitat and is thus considered to be vulnerable. More information is needed on this species.
