Nicolaus Pol (c. 1467 – 1532) was a Renaissance-era physician. He entered the service of Sigismund of Austria at Innsbruck in 1487, and continued to serve Sigismund's successors, emperors Maximilian and Charles until his death in 1532, at an age of about 65 years. He received a medical degree in 1494, and marked the inside cover of all the books in his library with Nicolaus Pol, doctor, 1494.
