The Master of Animals, Lord of Animals, or Mistress of the Animals is a motif in ancient art showing a human between and grasping two confronted animals. The motif is very widespread in the art of the Ancient Near East and Egypt. The figure may be female or male, it may be a column or a symbol, the animals may be realistic or fantastical, and the human figure may have animal elements such as horns, an animal upper body, an animal lower body, legs, or cloven feet. Although what the motif represented to the cultures that created the works probably varies greatly, unless shown with specific divine attributes, when male the figure is typically described as a hero by interpreters.

The Potnia Theron or Mistress of Animals is a widespread motif in ancient art from the Mediterranean world and the ancient Near East, showing a central human, or human-like, female figure who grasps two animals, one to each side. Although the connections between images and concepts in the various ancient cultures concerned remain very unclear, such images are often referred to by the Greek term Potnia Theron regardless of culture of origin.
