Flori Van Acker or Florimond Marie Van Acker (6 April 1858 – 14 March 1940) was a neo-romantic, impressionist Belgian painter, engraver, stamp designer and director of the Academy of Bruges.

[1] In line with the trend towards realism of the time, he went to live in the fishing town Knokke in 1882 where he made paintings of the life of the fishermen.

There was a large artist colony in Knokke at time which included Alfred Verwee, Louis Artan, Firmin Baes, Richard Baseleer, Alfred Bastien, Henri Cassiers, Franz Courtens and Paul-Jean Clays.

After several years of travel which took him, among others to the United Kingdom, France and Germany, he settled in Brussels.

As an amateur photographer, he was an active member of Bruges' Cercle Photographique.
