The Martínez–Troncoso–Zanelli (MTZ) black hole is a black hole solution for (3+1)-dimensional gravity with a minimally coupled self-interacting scalar field. It is named after Cristián Martínez, Ricardo Troncoso and Jorge Zanelli who proposed it in 2004. The event horizon is a surface of constant negative curvature, and the spacetime is asymptotically locally anti-de Sitter.
