Wladyslaw Cyganiewicz (November 20, 1891 – June 10, 1968), better known by the ring name Wladek Zbyszko (Polish: ['vwad?k 'zb??k?]), was a Polish catch wrestler, professional wrestler and strongman.
"Zbyszko" was his older brother Stanislaus's childhood nickname, borrowed from a fictional medieval knight in the novel Krzyzacy; both brothers used it as their ring name.
