Bruno Andreas Liljefors (14 May 1860 – 18 December 1939) was a Swedish artist. He is perhaps best known for his nature and animal motifs, especially with dramatic situations. He was the most important and probably most influential Swedish wildlife painter of the late nineteenth and early twentieth century. He also drew some sequential picture stories, making him one of the early Swedish comic creators.

He amassed a collection of animals to act as his living models. Ernst Malmberg recalled:

The animals seemed to have an instinctive trust and actual attraction to him. There in his animal enclosure, we saw his inevitable power over its many residents—foxes, badgers, hares, squirrels, weasels, an eagle, eagle owl, hawk, capercaillie and black game.

The greatness of Liljefors lay in his ability to show animals in their environment.
