Bubastis is an Ancient Egyptian city, located along the River Nile in the Delta region of Lower Egypt. It was a center of worship for the cat-goddess Bastet (also called Bast or even Bubastis), and it served as the capital of the nome of Bubastites.

It became a royal residence after Shoshenq I, the first ruler of the 22nd dynasty , was made pharoah in 952 BC. Bubastis was at its height during this dynasty and the 23rd . It declined after the Persian conquest by Cambyses II in 525 BC, which heralded the end of the 26th dynasty and the start of the Achaemenid dynasty.

Its ruins are near the modern city of Zagazig. There were archaeological expeditions to the ruins in 1886, 1887, and 1906, the last of which uncovered a 6th dynasty chapel and a 8th century BC temple.
