The 2018 Copa Chile (officially known as Copa Chile MTS 2018 due to its sponsorship), was the 39th edition of the Copa Chile, the country's national football cup tournament. Santiago Wanderers were the defending champions, but lost to Palestino in the second round of the competition. Palestino went on to become champions after defeating Audax Italiano in the final by an aggregate score of 4–2. Format The 2018 Copa Chile is based on a system of direct elimination with double-legged ties, similar to the Copa del Rey. As a novelty, after 6 years, clubs that are members of the Segunda División Profesional were included, and after 8 years, clubs of the ANFA were also included, such as these of Tercera División A and Tercera División B. Prizes The champions of this edition (or the runners-up, if the champions had already qualified) earned the right to compete in the 2019 Copa Libertadores, taking the Chile 4 berth. Besides, they also earned the right to play the 2019 Supercopa de Chile. Unlike previous Copa Chile editions, the runners-up were not entitled to a berth to the Copa Sudamericana.
