Andres Lignitzer (Andre Liegniczer) was a late 14th or early 15th century German fencing master. His name might signify that he came from Legnica, Silesia. While Liegniczer's precise lifetime is uncertain, he seems to have died some time before the creation of Codex Danzig in 1452. He had a brother named Jacob Lignitzer who was also a fencing master, but there is no record of any treatise Jacob may have authored. Paulus Kal include him, along with his brother, in his list of members of the Society of Liechtenauer in 1470.
Andre Liegniczer is best known for his teachings on sword and buckler, and some variation on this brief treatise is included in many compilation texts in the Liechtenauer tradition. He also authored treatises on armored fencing, dagger, and grappling, though these appear less frequently.
