Lusitanian (so named after the Lusitani or Lusitanians) was a Paleohispanic language that apparently belonged to the Indo-European family. There has been support for either a connection with the ancient Italic languages or Celtic languages. It is known from only five sizeable inscriptions, dated from circa 1 CE, and numerous names of places (toponyms) and of gods (). The language was spoken in the territory inhabited by Lusitanian tribes, from the Douro to the Tagus rivers, territory that nowadays falls in Portugal, and Western Spain.
