La Ley (Spanish, "The Law") is a Chilean pop rock band formed in Santiago by Andrés Bobe and Luis Alberto "Beto" Cuevas Olmedo with Mauricio Claveria, Rodrigo Aboitiz and Luciano Andrés Rojas. After a failed first album, Desiertos (1989), they released Doble Opuesto (1991), which appears as the official first album of the band. Singles like "Desiertos," "Tejedores de Ilusión," and "Prisioneros de la Piel" made them stars in Chile, Argentina and Mexico, especially after the release of La Ley, their second recording (1992). After Bobe's death in 1994, La Ley continued with a new guitarist, Pedro Frugone, and released two more albums, Invisible (1995) and Vértigo (1998). While the band was promoting Vertigo, Rojas and Aboitiz left the band.

Although their music was becoming more pop and less experimental, and the musicians dropped their appealing dark image and started dressing too trendily, the last La Ley albums, Uno 2000 and Libertad 2003, consolidated the band as one of the most important in Latin America, earning it a Latin Grammy award for each of the two albums. However, this style change also meant a loss of many fans.

La Ley also performed on MTV Unplugged in 2001, and released an album of the performance, which went on to win a Grammy award. In 2004, they released a greatest hits compilation (featuring three new songs) titled Historias e Histeria.

In 2005 the members of the band decided to take some time for their personal projects, and after a tour around Latin America, the band said goodbye in Buenos Aires on September 29, leaving open the possibility of a return in the future.
