Lidzbark Warmiński (; German: Heilsberg) is a town in the Warmian-Masurian Voivodeship in Poland. It is the capital of Lidzbark County. Lidzbark Warmiński was once the capital of Warmia and formerly its largest city. The city itself was a rich center of faith and culture and was known as the Pearl of Warmia. For a long period of time it was under the control of the Bishops of Warmia and it was also a major economic center, only resigning its importance to the nearby city of Braniewo. The Warmian Bishop's Castle is considered to be a great artistic and historical value in the world and has been recognised as a historical monument by the Polish government.
