Krystyn Szelejewski (d. 1457/1459) was a Polish nobleman and the castellan of Krzywià Â.
Krystyn was probably son of Pietrasz Wierzbieà Âski, burgrave of Koà Âcian (mentioned in 1408 and 1409), and Tomisà Âawa of Szelejewo near Borek. He had brothers Dziersà Âaw, Szymon and Jan.
Before 26 March 1443 Krystyn Szelejewski became the castellan of Krzywià Â. In hierarchy of office it was very low castellany. Probably he gained the castellany thanks to Krzesà Âaw KurozwÃÂcki, who wanted awarded him for his contribution as a burgrave of Koà Âcian.
Krystyn was still alive on 8 March 1457. He died before 10 April 1459, because on this day Piotr Ràbià Âski was mentioned as a castellan of Krzywià Â.
Krystyn before 1437 married Jadwiga. He had three sons: Piotr (fl. 1465), probably died young, Mikoà Âaj (d. after 1505) and Krystyn (d. after 1494), vice-chamberlain (wicepodkomorzy) of Koà Âcian (1485-1491).
