Ras Lanuf (/ˌrɑːs ləˈnuːf/ (Arabic: راس لانوف Raʾs Lānūf,[1] also: Ra’s al-Unūf [2])) is a Mediterranean town in northern Libya, on the Gulf of Sidra in Tripolitania.

Some historians claim it is 40 km west of El Agheila, while others place Arae Philaenorum near Ra's Lanuf,[5] and the modern Italian commemorative arch featuring the Philaeni stood here before its destruction in 1973.

The town's structure was based on a functional hierarchy, containing three centers forming public zones with community facilities extending to the Mediterranean coast; these were in turn surrounded by high-rise housing blocks.

[10] On 27 March rebels retook control of Ra's Lanuf as part of a rapid advance as 24 hours earlier they had retaken the strategic towns of Brega and Ajdabiya,[11] but within a matter of days rebel forces retreated from the city once more in the face of a new government counter-offensive.

On 23 August, rebels recaptured Ra's Lanuf from government loyalists and continued their advance towards Bin Jawad and Sirte.

The Port of Ra's Lanuf consists of a small harbor, operated by the Veba Oil Company and RASCO.
