Paleo-Laplandic is a hypothetical group of extinct but related languages spoken in Sápmi (northern Scandinavia).

Many words relating to the environment or reindeer such as ája ("spring of water") are likely loanwords from Paleo-Laplandic into Sámi.

Linguist Jurij Kuzmenko [de] compared them with the Pre-Germanic substrate words but found no similarities aside from a distinction between central and peripheral accentuation.

[5] A large amount of Sami root words that start with the Č or K sounds tend to be from Paleo-Laplandic.

Paleo-Laplandic, like Sami, had many different words for describing different types of animals, weather, and geographical features they often encountered.
