Robert Julius Tommy Jacobsen (4 June 1912, Copenhagen - 26 January 1993, Tågelund) was a Danish sculptor and painter.

He lived in France from 1947 - 1969. From 1962 - 1981 he was professor at the Kunstakademie der Bildenden Künste, Munich. In 1969 he moved to Tågelund, west of Egtved, Denmark. From 1976 to 1985 he was professor at the Royal Danish Academy of Art, Copenhagen. From 1986 to 1991 he worked with Jean Clareboudt to create a sculpture park at Tørskind Gravel Pit near Egtved and Vejle. He worked closely together with his friend and son in law, Bernard Leauté. Jacobsen also had a connection to Asger Jorn and the CoBrA artists, but he never was a member of their group. He died in 1993 at home in Tågelund.

The Danish Robert award was named after him. It was planned to raise a 60 meter high sculpture in Copenhagen in the year 2012, financed by Robert Jacobsen's foundation but the city council did not want the sculpture.

... everyone, of course, must know with whom he is dealing. A former badminton champion, a film actor, a former sailor, a whale butcher, an ex-barman, an antiquarian, a musician (jazz to be sure) a chaufeur, a confectioner and a croupler, a grandfather at thirty - seven, the Danish Robert Jacobsen is certainly one of the best sculptors of our time, a worthy successor of the Rumanian Brâncuşi, of the Russian Pevsner, of the American Calder and of one or two others whom you may choose according to you tastes...
