The Trango Towers (Urdu: ٹرینگو ٹاورز) are a family of rock towers situated in the Gilgit-Baltistan region, in northern Pakistan. The Towers have some of the world's largest cliffs and offer some of the most challenging big wall climbing opportunities. Each year, climbers from around the world embark on expeditions to the Karakoram region to climb these granite faces. The Trango Towers are situated to the north of the Baltoro Glacier and are part of the Baltoro Muztagh, which is a sub-range of the Karakoram. The highest point within the group is the summit of Great Trango Tower at 6,286 m (20,623 ft), the east face of which features the world's greatest nearly vertical drop.

All of the Trango Towers lie on a ridge, running northwest to southeast, with Trango Glacier to the west and the Dunge Glacier to the east. Great Trango itself is a large massif, with three distinct summits: Main (6,286 m (20,623 ft)), East (6,231 m (20,443 ft)), and West (6,223 m (20,417 ft)). It is a complex combination of steep snow/ice gullies, steeper rock faces, and vertical to overhanging headwalls, topped by a snowy ridge system.

Just northwest of Great Trango is the Trango Tower (6,239 m (20,469 ft)), often called "Nameless Tower". This is a very large, pointed, rather symmetrical spire which juts 1,000 m (3,300 ft) out of the ridgeline. North of Trango Tower is a smaller rock spire known as "Trango Monk." To the north of this feature, the ridge becomes less rocky and loses the large granite walls that distinguish the Trango Towers group and make them so attractive to climbers; however, the summits do get higher. These summits are not usually considered part of the Trango Towers group, though they share the Trango name. Trango II (6,237 m (20,463 ft)) lies northwest of the Monk, and the highest summit on the ridge, Trango Ri (6,363 m (20,876 ft)), lies northwest of Trango II.

Just southeast of Great Trango (really a part of its southeast ridge) is the Trango Pulpit (6,050 m (19,850 ft)), whose walls present similar climbing challenges to those of Great Trango itself. Further, to the south is Trango Castle (5,753 m (18,875 ft)), the last large peak along the ridge before the Baltoro Glacier.

Overall, the Trango Towers group has seen some of the most difficult and significant big wall climbs ever accomplished, due to the combination of altitude, total height of the routes, and the steepness of the rock. All of the routes are highly technical climbs.

Trango (Nameless) Tower was first climbed in 1976 by the British climber Joe Brown, along with Mo Anthoine, Martin Boysen, and Malcolm Howells. There are at least eight separate routes to the summit.

After several unsuccessful attempts, the second and third ascents were achieved in 1987, with the opening of two new routes: The Slovenian Route, better known as the Yugoslav Route, a pure, clean, logical crack route on the south-southeast face, by Slavko Cankar, Franc Knez [sl] and Bojan Šrot, and the Great Overhanging Dihedral Route, a spectacular and technical ascent on the western pillar, by Swiss/French team Michel "Tchouky" Fauquet, Patrick Delale, Michel Piola and Stephane Schaffter.

The first route that was freed (using fixed lines to return to a base each night), in 1988, was the Yugoslav Route by the German team Kurt Albert, Wolfgang Güllich, and Hartmut Münchenbach.
