Władysław Mazurkiewicz (23 September 1871 – 6 August 1933) was a Polish physician and professor of pharmacognosy and medical botany at the University of Warsaw.

He was a member of a student circle which concerned itself with politics and self-education, as well as the Polish Socialist Party (PPS).

Following the completion of his studies, he temporarily stayed in Saint Petersburg at the request of the PPS to, together with Aleksander Sulkiewicz, help Józef Piłsudski escape from a mental hospital in the city, to which Piłsudski had been transferred from the Warsaw Citadel after feigning mental illness.

Mazurkiewicz used his father's contacts in Saint Petersburg to obtain employment as a doctor in the hospital and soon became head of the psychiatry department.

During the Russian Revolution of 1905 he kept in contact with the PPS leadership in Congress Poland, smuggled underground publications over the border and was nominated to command the Łomża district in the event of an uprising.

In 1905 Mazurkiewicz moved to Lviv, where he became an assistant to Professor Leon Popielski at the Institute of Pharmacology and Pharmacognosy.

On 16 August 1914, Emperor Franz Joseph I appointed him as an associate professor of pharmacognosy at the University of Lviv.
