Historically, Solukhumbu was part of Kirata Kingdoms in early and medieval era. It was a part of Majh Kirat Khambuwan (central province or region of Kirat Kingdoms).

Before the unification of Nepal by king of Gorkha, what is now Solukhumbu district was part of Chaudandi of Majh Kirat (Khambuwan). In 1773 AD the King of Gorkha attacked and absorbed it into Nepal.

The Solukhumbu district was established in 1962, out of the old East No. 3 district. Before 1962, present-day Solukhumbu, Okhaldhunga and some parts of Khotang previously constitute district "East No. 3". Solu and Rawa thums (counties) were carved out of East No. 3 to create Solukhumbu District.
