Arvid Oskar Gustaf Genetz (1 July 1848— 3 May 1915) was a Finnish politician, poet and linguist.

He and his wife had six children: sons Juho, Arvi, Niilo and Paavo, and daughters Laura and Helvi.

In historical linguistics, he was the first one who realized that the Sami exchanged many loans words with the Baltic Finnic languages.

In order to research Finno-Ugric languages, Genetz made several expeditions to the White Sea region of Karelia, the Kola Peninsula and Siberia.

[6] Arvid Genetz worked with native speakers to translate the Gospel of Matthew into Kola Sámi.
