Žemaitkiemis meteorite is an ordinary chondrite that fell near Žemaitkiemis, Lithuania at about 8:33 pm on 2 February 1933. Using the argon–argon dating method, scientists have calculated its age to be about 520 million years.

In total, 20 fragments with a combined weight of were collected and donated to the Vytautas Magnus University. The largest pieces weighted 7258and. Two other fragments were gifted later – and – to the Institute of Geology and Geography in Vilnius. There were also reports of a fragment found about from Žemaitkiemis in 1938.
