Žaliakalnis (literally, "the green hill") is a neighbourhood and eldership (Lithuanian: Žaliakalnio seniūnija) in Lithuania's second largest city, Kaunas.

Žaliakalnis is located north of the old town and the city center area, between the Neris and Girstupis valleys.

In Frandsen's plan, Žaliakalnis was to be an important part of Kaunas, where all the city's administrative functions would be located.

This part of the concept was not fulfilled, although the neighbourhood quickly became very popular and many modern residences were built.

Žaliakalnis was home to some well-known Lithuanian writers and artists such as Balys Sruoga, Vincas Krėvė-Mickevičius, Ieva Simonaitytė, Kazys Binkis, Kipras Petrauskas, President Valdas Adamkus grew up here.
