Bethlehem is located at an elevation of about 775 meters (2,543 ft) above sea level, 30 meters (98 ft) higher than nearby Jerusalem.

The city is located 73 kilometers (45 mi) northeast of Gaza City and the Mediterranean Sea, 75 kilometers (47 mi) west of Amman, Jordan, 59 kilometers (37 mi) southeast of Tel Aviv, Israel and 10 kilometers (6.2 mi) south of Jerusalem. Nearby cities and towns include Beit Safafa and Jerusalem to the north, Beit Jala to the northwest, Husan to the west, al-Khadr and Artas to the southwest, and Beit Sahour to the east. Beit Jala and the latter form an agglomeration with Bethlehem. The Aida and Azza refugee camps are located within the city limits.

In the center of Bethlehem is its old city. The old city consists of eight quarters, laid out in a mosaic style, forming the area around the Manger Square. The quarters include the Christian an-Najajreh, al-Farahiyeh, al-Anatreh, al-Tarajmeh, al-Qawawsa and Hreizat quarters and al-Fawaghreh — the only Muslim quarter. Most of the Christian quarters are named after the Arab Ghassanid clans that settled there. Al-Qawawsa Quarter was formed by Arab Christian emigrants from the nearby town of Tuqu' in the 18th century. There is also a Syriac quarter outside of the old city, whose inhabitants originate from Midyat and Ma'asarte in Turkey. The total population of the old city is about 5,000.
