Julpolska, also known as Nu ha vi ljus här i vårt hus, is a Christmas song with lyrics by Rafael Hertzberg (1845-1896) and music by Johanna Ölander (1827-1909). Song lyrics describe Christmas Eve, dated from a time when the Christmas goat at many places still was the giftbringer, not Santa Claus. The song was also used in the 1987 film Mer om oss barn i Bullerbyn.
