The Ci Banten, or Ci Peteh, is a river in Banten province on the island of Java, Indonesia.
The rivers in Banten, the westernmost province of Java, run roughly parallel to each other. The main rivers are the Peteh, called the Banten on the lower reaches near the city of Kota Banten; the Ujung, which enters the sea at Pontang; the Durian, which enters the sea at Tanara; the Manceuri; and the Sadane, which rises in the mountainous region of Priyangan and in 1682 formed the border between the Dutch East India Company (VOC) territory and Batavia (modern Jakarta).
