Jounieh (Arabic: جونيه, or Juniya, جونية) is a coastal city in Keserwan District, about 16 km (10 mi) north of Beirut, Lebanon. Since 2017, it has been the capital of Keserwan-Jbeil Governorate. Jounieh is known for its seaside resorts and bustling nightlife, as well as its old stone souk, ferry port, paragliding site and gondola lift (le téléphérique), which takes passengers up the mountain to the shrine of Our Lady of Lebanon in Harissa.

Above Jounieh, and on the way to Harissa, a small hill named Bkerké (Arabic: بكركي, or Bkerki), overlooking the Jounieh bay, is the seat of the Patriarch of the Maronite Catholic Church of Lebanon. Residents of Jounieh and the surrounding towns are overwhelmingly Maronite Catholics. Maameltein is a district of Ghazir village.

The history of Jounieh goes back to the time of the Phoenicians. The town was an important trading center along the Lebanon coastline. In those days the port was an important one during winter, as it served as a safe spot for ships sailing south to Byblos. This gave the place the name of the name of "Palaebyblus" that means 'Before Byblos”. In his geographic description the Greek historian Strabo mentions this town.

The reason few remains can be seen today is due to the fact that during the Roman and Byzantine period, many buildings and structures were built over the Phoenicians buildings and some are still visible today.

The medieval Muslim historian al-Idrisi (d. 1165) notes that Jounieh was a sea fortress whose inhabitants were Jacobite Christians. The Syrian geographer Yaqut al-Hamawi (d. 1226) called it a dependency of Tripoli.

In the sixth part of The Introduction to Jounieh in the Mid Nineteenth Century, Professor Butrus Al-Boustani said: “Jounieh is a place on the Keserwan coast which has warehouses, stores, and a dye house. Ships and boats bring supplies and its grain trade is very popular. Thus a district of the following villages: Sarba, Ghadir, and Harat Sakhr was named for it. Its total population is 2,500. Jounieh itself is not a residential area but mainly a commercial district whose workers come from neighboring towns.”

Jounieh was connected with neighboring areas by roads built for carriages. So it was connected with Bkerké and beyond it during the rule of Dawud Basha, the ruler of Mount Lebanon. It was connected to Ghazir between 1867 and 1868 despite the objection of Ghazir's residents. Another road connected Jounieh to the Beirut Bridge during the rule of Rustum Basha. To the north it was connected by a carriage's road until Batroun during the rule of Wasa Basha (1883–1892). In 1892, Jounieh was connected to Beirut via a railroad that had stations between the two locations, three of which in Jounieh and its environs: Sarba, Jounieh, and Mu’amilitain at the end of the line, which facilitated the transportation of goods and passengers from and to the Governorate of Beirut. In 1876, the number of shops exceeded 300, five silk factories, three rest houses, a mill, three juice factories, an artificial ice factory, a bank known by its owner's name "Bank Baghos", and a group of small sailboat construction sites.

In 1906, according to the Guide to Lebanon by Ibrahim Beik Al-Soud, the population of Jounieh was 2,400, and it had a silk factory owned by the Nasras, a silkworms choker owned by Moussa de Franj, a silk factory owned by the heirs of Rizkallah and Abdul Ahad Khadra which had 190 wheels and produced 10,000 cocoons, 330 domestic animals, and owned 80 carriages. According to the records of the Keserwan Governorate, the town of Ghadir, in 1914, had 433 corporations and its population was 1,263. The town of Sarba had 213 commercial institutions and its population was 1,714. In Harat Sakhr, there were 165 corporations and its population was 808. In Sahil ‘Alma, there were 21 corporations its population reached 187. Jounieh had seen noticeable prosperity after France and the Maronite Patriarchy supported the opening a port for commercial ships which became (with the Al-Nabi Younes Port on the Chouf Coast) the official port of Mount Lebanon.
