Søndfjords Avis was a Norwegian newspaper published in Florø in Sogn og Fjordane between 1898 and 1909. It was a publication of the liberal Venstre political party and took a radical stance on political matters, such as advocating republicanism. For this, it took a significate drop in readership from 1905 following the Norwegian monarchy plebiscite. A digital archive of the newspaper is available at the University of Bergen.
