The Old City of Gaza is the historical center of Gaza City, in the Gaza Strip. For much of recorded history it has been the southernmost coastal city in the region of Palestine, occupying a strategic position on ancient trade route of the Via Maris, between Egypt and the Levant. Throughout its history, Gaza has been ruled by various empires, including the Philistines, Egyptians, Assyrians, Babylonians, Romans, and Ottomans. Following Israeli bombardment during the ongoing Gaza–Israel conflict, the Old City has been described in 2024 as "a vast field of ruins".

The city's origins trace back to around 3000 BCE, when it was first established by the Canaanites. Gaza rose to prominence due to its location on the Via Maris trade route that links Africa and Asia, serving as a hub for merchants and travelers. During the Roman and Byzantine periods, it grew as a center for the trade of spices and perfumes. It continued to play an important role under Islamic rule, was briefly conquered by the Crusaders, and later became part of the Ottoman Empire in 1516. Much of the Old City has been destroyed by Israeli bombardment during the ongoing Gaza–Israel conflict.

The Old City of Gaza is divided into four main quarters, some of which have subdivisions. Three of these quarters — Tuffah, Daraj, and Zaytun — were located within the walls of the ancient city, while the southeastern quarter, as-Saja'iyyah, developed later, mostly outside its walls:

• Daraj Quarter ("The Stairs Quarter"): Located in the northwest (generally west), this is the oldest part of the city, sometimes referred to as the old city of Gaza proper. It is known for its narrow streets and traditional homes. It sits on an hill about 20 meters above the surrounding plain and other parts of the city. The name likely comes from the stairs that led up to it or the sensation of climbing stairs when approaching the area.
• Zaytun Quarter ("The Olive Quarter"): Situated in the southwest (generally south), this quarter is named after its historical olive groves. It is the largest quarter within the old city walls. It contains the St. Porphyrius Church. The medieval Khan az-Zayt formed the historical border between the Zaytun Quarter and the Daraj Quarter; this was demolished under Djemal Pasha during the later years of Ottoman rule, and replaced with a road currently named Umar al-Mukhtär Street which now forms the boundary between the two quarters.
• Tuffah ("The Apple Quarter"): Located in the northeast (generally north), this quarter is known as the Apple Quarter. The southern part of this quarter, called ad-Dabbäghah, was historically the tanners' neighborhood, which was situated near the Ottoman-era slaughterhouse.

• Shuja'iyya: This southeastern quarter, which developed during the Middle Ages, mostly lies outside the ancient city walls. Its location outside the walls allowed it to expand significantly, eventually surpassing the Zaytun Quarter in size. The quarter is subdivided into two parts: al-Judaydah (also known as Saja'iyyat al-Akrād, or "The Saja'iyyah of the Kurds") in the northeast and at-Turkmän in the south.

The Old City of Gaza is renowned for its architectural landmarks, many of which date back to the Mamluk and Ottoman periods. The dense urban fabric includes mosques, churches, bathhouses, and markets that showcase a blend of Byzantine, Mamluk, and Ottoman architectural styles. Despite modern development, the Old City retains many elements of its historical layout.

• Great Mosque of Gaza (Al-Omari Mosque) – Originally a Byzantine church, converted into a mosque during the Islamic period.
• Church of Saint Porphyrius – A Byzantine-era church serving the local Greek Orthodox community.
• Sayed al-Hashim Mosque – said to contain the tomb of Hashim ibn Abd al-Manaf, Muhammad's great grandfather who died in Gaza.
• Hamam al-Sammara – A traditional bathhouse from the Mamluk period.
• Qasr al-Basha (Napoleon's Fort) – An Ottoman palace where Napoleon Bonaparte is said to have stayed.
• Gold Market (Souk Al-Qaysariyya) – A historic market specializing in gold and jewelry.
• Old City Walls – Remnants of the fortifications that once encircled the city.
