Sântămăria-Orlea (Hungarian: Őraljaboldogfalva, German: Liebfrauen) is a commune in Hunedoara County, Transylvania, Romania.

It is composed of nine villages: Balomir (Balomir), Bărăștii Hațegului (Baresd), Bucium-Orlea (Bucsum), Ciopeia (Csopea), Săcel (Szacsal), Sânpetru (Szentpéterfalva), Sântămăria-Orlea, Subcetate (Hátszegváralja), and Vadu (Vád).

It is situated in the historical and ethnographical area known as Țara Hațegului, 3 km (1.9 mi) southeast of its hub, the town of Hațeg.

This community is notable as the place where, in the late 19th century, Ilona von Felsö-Szilvás discovered fossilized dinosaur bones that had become exposed in a hillside on her the family’s estate near Sânpetru (called then Szentpéterfalva).

[2][3] Ilona and her brother, Baron Franz Nopcsa von Felsö-Szilvás, were intrigued by the discovery.
