Çanakkale is a town and seaport in Turkey, in Çanakkale Province, on the southern (Asian) coast of the Dardanelles (or Hellespont) at their narrowest point. The population of the town is 106,116 (2010 estimate). The current mayor is Ülgür Gökhan (CHP).

Çanakkale Province, like Istanbul Province, has territory in both Europe and Asia. Ferries cross here to the northern (European) side of the strait.

The city is the nearest major town to the site of ancient Troy. The "wooden horse" from the 2004 movie Troy is exhibited on the seafront. Çanakkale is the second city to be situated on two continents after Istanbul. However Çanakkale is closer to mid-division than Istanbul. There is a Jewish community.

The Byzantine name for Çanakkale was Dardanellia, from which the English name Dardanelles is derived.

Çanakkale was an Ottoman fortress called Kale-i Sultaniye or Sultaniye kalesi (Fortress of the Sultan). It later became known for its pottery, hence the later name Çanak kalesi 'pot fortress' or 'Çanakkale.

Ancient Abydos, where the story of Hero and Leander takes place, is to the north of Çanakkale.

The first inhabitants of the city, which hosted many civilizations, lived on the Biga Peninsula in the Last Chalcolithic Age c. 6000 years ago. However, very little is known about the identity and lifestyle of these early settlers. According to some excavations and research, the earliest settlements in the region were established at Kumtepe. It is supposed that Kumkale was established in 4000 BC and Troy between 3500-3000 BC. The real history of Çanakkale started with Troy.

Later the Aeolian Greeks settled on that important land in the 8th century BC and established many trade colonies in the region called Aeolis. The region came under the control of the Lydians in the 7th century BC and under the control of the Persians in the 6th century BC. Aeolis went under the control of the Macedonians as Alexander the Great defeated the Persians by the Granicus River of the region in the Battle of the Granicus on his way to Asia. The region went under the reign of the Kingdom of Pergamon in the 2nd century BC.

The western part of the Biga Peninsula where ancient Troy is stiuated was called Troas. Alexandria Troas, an important settlement of the region, was a free trade port and a rich trade center during Roman times. Later in the 2nd century AD, the region was attacked by Goths from Thrace. During the 7th and 8th centuries, in order to attack Constantinople (modern Ýstanbul) the Arabs passed the strait a few times and came up to Sestos. At the beginning of the 14th century the Karasids dominated the Anatolian part of the strait. During the first half of that century Demirhan Bey from Karasids attempted to dominate the region. The Ottomans gained control of Gallipoli in 1367.

In 1915, during the First World War, Great Britain and France attempted to to capture the Ottoman capital of Constantinople and secure a sea route to Russia. Known as the The Gallipoli Campaign, or the Dardanelles Campaign, in Turkey it is referred to as the Battle of Çanakkale (Turkish: Çanakkale Savaþý), in particular the sea battle which took place on March 1915 where the Royal Navy was repulsed by Turkish forces. During the naval battles, Joule, AE2, Triumph, Ocean and HMS Goliath were among the crafts sunk by Turkish forces.
