Luis Fernando Suárez Guzmán (born 23 December 1959) is a Colombian football manager and former player who played as a defender.

Suárez has managed in six Latin American countries: Colombia, Ecuador, Peru, Honduras, Mexico and Costa Rica.

Suárez led the Ecuador national team to the round of 16 at the 2006 FIFA World Cup and won the 1999 Colombian championship with Atlético Nacional.

Reaching the second round by inflicting defeats on Poland and Costa Rica, they lost to England 1–0 after a David Beckham free kick sailed into the net.

Suárez got off to the worst possible start for the 2010 World Cup qualifiers, losing 1–0 at home to Venezuela and receiving a 5–0 hammering by Brazil.
