Adam Stanisław Grabowski (Latin: Adamus Stanislaus Grabowski; Gr. Butzig (Wielki Buczek), near Pr. Friedland (now Debrzno), 3 September 1698 – 15 December 1766, Heilsberg (now Lidzbark Warmiński)), of the Zbiświcz coat-of-arms, was Bishop of Chełmno 1736–39, Bishop of Kujawy 1739–41, Prince-Bishop of Warmia 1741–66.
Grabowski was the son of Schlochau assessor (Człuchów district judge) Andreas Theodor Grabowski and his wife Barbara Sofia von Kleist. He attended Jesuit schools in Chojnice and Toruń, then studied law in Rome. For a time he was a court scribe (pisarz sądowy) in Skarszewy, then was secretary to Crown Deputy Chancellor Andrzej Lipski and became an official in the Crown Chancellery.
In 1730 Grabowski took holy orders and, as a trusted associate of Chancellor Jan Aleksander (?) Lipski, quickly accumulated lucrative benefices. He received canonicates in Lwów and Włocławek, a deanery in Chełmno, and presbyteries in Jaworowo, Skaryszew and Tujce. In 1733 he became the Poznań suffragan.
