Juan López Fontana (15 March 1908 – 4 October 1983) was a Uruguayan professional football manager who won the 1950 FIFA World Cup as the head coach of the Uruguay national team.

His hometown is the home of Estadio Centenario where Uruguay had won the 1930 FIFA World Cup under head coach at the time Alberto Suppici.

Uruguay drew Spain and beat Sweden going into a final match at the Estádio do Maracanã with Brazil, who only needed a draw to win their first World Cup.

At the 1954 FIFA World Cup in Switzerland, López coached his side to a place in the semifinal, beating traditional powerhouses Czechoslovakia, Scotland and England along the way.

By 1962, López was coaching the national side as part of a committee including Hugo Bagnulo and Roberto Scarone,[1] and at the 1962 FIFA World Cup worked alongside Juan Carlos Corazo.
