Laurentius Christophori Hornaeus or also known as Lars Christophri Hornæus (1645 – April 27, 1719), was a priest of the Church of Sweden.
Olaus Rufinius died in 1672, and Lars was appointed as the new "assistant minister" of Ytterlännäs.
Lars and Elizabeth had a son: Jöns Hornaeus (1715–1778), a minister who documented the witch trials of his grandfather.
He was buried under the old church in Ytterlännäs where a hatch in the floor between the altar and the door to the sacristy leads to his still preserved grave.
Lars Larsson Hornaeus took over his father's pastorate in 1719 and led the congregation until his death in 1751.
