Carl Blos was a German portrait, landscape and genre painter.

He began his art lessons from 1878 to 1880, at the Kunstgewerbeschule (arts and crafts school) in Karlsruhe. From 1881 to 1883, he continued his studies at the Academy of Fine Arts there, under the direction of Karl Hoff. By 1887, he had completed his studies at the Academy of Fine Arts, Munich, where his primary instructor was Wilhelm Lindenschmit. During his last two years there, he was also employed in Lindenschmit's workshop.

He was awarded the Academy's medal in 1884, and received a small gold medal at the Große Berliner Kunstausstellung of 1896.

Later, he became a member of the moderately progressive Luitpold-Gruppe [de]. In 1902, he was named a Professor at his alma mater, the Munich Academy.

In 1905, he was awarded the Großen Medaille in 1905, and the Lenbach Prize of the city of Munich in 1937.
