816 Juliana is a minor planet orbiting the Sun. It measures 59.85k in diameter. It was discovered on 8 February 1916 by Max Wolf at the Landessternwarte Heidelberg-Königstuhl Observatory in Heidelberg, Germany.
Wolf probably chose the name to honour Princess Juliana (later Queen Juliana of the Netherlands); he had previously named 392 Wilhelmina after her mother.[2]
