Tor Aulin (10 September 1866 – 1 March 1914) was a Swedish violinist, conductor and composer.

Aulin studied music at the Royal College of Music in Stockholm (1877-1883) under Carl Johan Lindberg [sv] and then in the Conservatory of Berlin (1884-1886) with Émile Sauret and Philipp Scharwenka.

From 1889 to 1892 Aulin served as concertmaster of the Royal Swedish Opera in Stockholm.

Along with Wilhelm Stenhammar, Aulin spearheaded a revival in interest in the work of Franz Berwald, and as soloist he premiered some of Stenhammar's works for violin and orchestra.

His sister, Laura Valborg Aulin, was a pianist and composer whose output included two string quartets, in F major and E minor, among other works.
