Przemko of Ścinawa (Polish: Przemko ścinawski) (1255/65 – 26 February 1289) was Duke of Żagań from 1278 to 1284 and Duke of Ścinawa from 1284 until his death.
He was the third and youngest son of Konrad I, Duke of Głogów by his first wife Salome, daughter of Duke Władysław of Greater Poland.
After his father's death in 1274, Przemko was placed under the care of his older brother Henry III. Only in 1278 he received the Duchy of Żagań (which included Żagań, Szprotawa and Nowogród Bobrzański) as an independent ruler. By 1281 he paid homage to Henry IV Probus, Duke of Wroclaw.
As a result of pressures from Henry IV Probus, in 1284, Przemko and his brother Konrad II the Hunchback, Duke of Ścinawa, exchanged their lands: Przemko assumed rule over Ścinawa and Konrad II took Żagań. This was maybe because Henry IV preferred in the borders of his domains the most trustful Przemko, who, like his brother Henry III, was a faithful follower of Henry IV's politics, supporting him in all his major projects, including in the conflict with the Bishop Thomas II of Wroclaw. When Henry IV Probus took control over Kraków after the death of Leszek II the Black in 1288, he could count on the support of the Duke of Ścinawa.
Przemko died during the Battle of Siewierz between Henry IV Probus and the coalition formed by Duke Bolesław II of Płock and Duke Władysław I the Elbow-high of Kuyavia. According to the Chronicle of Jan Długosz, the exact date of the battle was 26 February 1290; however, 26 February 1289 seems a more likely date, and is given by other sources.
