Luas (/ˈluːəs/, Irish: [ˈl̪ˠuəsˠ]; meaning 'speed') is a tram system in Dublin, Ireland. There are two main lines: the Green Line, which began operating on 30 June 2004, and the Red Line which opened on 26 September 2004. Since then, the red line has been extended and split into different branches further out of the city and the green line has been extended north and south as a single line. Since the northern extension of the green line in 2017, the two lines intersect in the city centre. The system now has 67 stops and 42.5 kilometres (26 mi 719 yd) of revenue track, which in 2024 carried 54 million passengers, an increase of 12% compared to 2023. The two lines carried 55 million passengers in 2025.

Luas is operated by the KeolisAmey consortium, having been operated from commencement to August 2026 by Transdev, under tender from Transport Infrastructure Ireland (TII) (prior to the RPA merger with the National Roads Authority to form TII, the tender was originally under the defunct Railway Procurement Agency. The Luas was a major part of the National Transport Authority's strategy (2000–2016). Four extensions to the initial Luas lines have been completed. Construction of a six-kilometre (3+1⁄2-mile) extension of the Green line through the north city centre to Broombridge, which linked both Green and Red lines, began in June 2013 and opened to passengers in December 2017. This is the extension route previously known officially as BXD.
