The Tünel (, designated as the F2 line on the Istanbul transport map) is a historic underground rubber-tyred funicular line in Istanbul, Turkey. It has two stations, connecting Karaköy and Beyoğlu. The tunnel runs uphill from near the confluence of the Golden Horn with the Bosphorus and is about long. It was inaugurated on 17 January 1875, making it the second oldest underground urban railway in the world, after the London Underground (1863).
