Pite Sámi or Arjeplog Sámi is a Sámi language traditionally spoken in Sweden and used to be spoken in Norway. It is a critically endangered language that has only about 25–50 native speakers left and is now only spoken on the Swedish side of the border along the Pite River in the north of Arjeplog and Arvidsjaur and in the mountainous areas of the Arjeplog municipality.

Sámi languages, in English also rendered as Sami and Saami, are a group of Uralic languages spoken by the Indigenous Sámi people in Northern Europe. There are, depending on the nature and terms of division, ten or more Sami languages. Several spellings have been used for the Sámi languages, including Sámi, Sami, Saami, Saame, Sámic, Samic and Saamic, as well as the exonyms Lappish and Lappic. The last two, along with the term Lapp, are now often considered pejorative.
