波罗的-斯拉夫语族（Baltic-Slavic languages）是印欧语系中波罗的语族和斯拉夫语族的合称。波罗的语族的语言和斯拉夫语族的语言共同点较多，两者较为接近。但波罗的诸语和斯拉夫诸语是否是同一语族，目前仍然有争议^[2]^[3]^[4]

Those scholars who accept the Balto-Slavic hypothesis attribute the large number of close similarities in the vocabulary, grammar, and sound systems of the Baltic and Slavic languages to development from a common ancestral language after the breakup of Proto-Indo-European. Those scholars who reject the hypothesis believe that the similarities are the result of parallel development and of mutual influence during a long period of contact.

Thus I assume that Balto-Slavic split into three identifiable branches, each of which followed its own course of development.
