Lars "Lasse" Johansson (1638 – August 13, 1674), usually referred to under his pseudonym Lucidor (), was a Swedish baroque poet. He is remembered for his burlesque poetry that is seen as foreshadowing that of Johan Runius and, especially, Carl Michael Bellman, and for his dramatic death in a tumultuous brawl at the Fimmelstången tavern in Gamla stan in Stockholm. Lasse Johansson wrote under several different pseudonyms, but of these Lucidor (or , "Lucidor the Unfortunate", as he called himself on occasion) is the one under which he is commonly known today.
