Jednorożec is a village in Poland, Mazovian Voivodeship, the seat of a rural gmina with the same name. The founding legend of the village has it that a beekeeper once saw a unicorn when removing honey from the hives in the royal hunting reserve. The owner of the forest, Prince Janusz III of Masovia ordered a hunting lodge to be built in that spot, named "Jednorożec" ("Unicorn").
Inspired by the legend, the coat of arms of the gmina shows a unicorn rampant argent, armed, craned and unguled or, with two honeybees in the upper corners. The field is vert.
