Acre (ˈɑːkər,_ˈeɪkər ), known locally as Akko (עַכּוֹ, ʻAkkō) or Akka (عكّا, ʻAkkā), is a city in the coastal plain region of the Northern District of Israel.
The city occupies a strategic location, sitting in a natural harbour at the extremity of Haifa Bay on the coast of the Mediterranean's Levantine Sea. Aside from coastal trading, it was an important waypoint on the region's coastal road and the road cutting inland along the Jezreel Valley. The first settlement during the Early Bronze Age was abandoned after a few centuries but a large town was established during the Middle Bronze Age. Continuously inhabited since then, it is among the oldest continuously inhabited settlements on Earth. It has, however, been subject to conquest and destruction several times and survived as little more than a large village for centuries at a time.
Acre was a hugely important city during the Crusades as a maritime foothold on the Mediterranean coast of the southern Levant, and was the site of several battles, including the 1189–1191 Siege of Acre and 1291 Siege of Acre. It was the last stronghold of the Crusaders in the Holy Land prior to that final battle in 1291.
The population of the town was dramatically changed as a result of the 1948 Arab–Israeli War; it had been almost entirely Muslim and Christian until May 1948, until three quarters of the population fled; it was then resettled by Jewish immigrants. In present-day Israel, the population was in , made up of Jews, Muslims, Christians, Druze, and Baháʼís. In particular, Acre is the holiest city of the Baháʼí Faith in Israel and receives many of that faith every year. Acre is one of Israel's mixed cities; thirty-two per cent of the city's population is Arab. The mayor is Shimon Lankri, who was re-elected in 2018 with 85% of the vote.
The etymology of the name is unknown, but apparently not Semitic. A folk etymology in Hebrew is that, when the ocean was created, it expanded until it reached Acre and then stopped, giving the city its name (in Hebrew, ad koh means "up to here" and no further).
