The 2005 ICC Americas Under-19 Championship was an international cricket tournament held in King City, Ontario, from 8 to 13 August 2005.

The United States finished the tournament undefeated to win its first title, and consequently qualified for the 2006 Under-19 World Cup in Sri Lanka.

The team had nearly been barred from playing, as part of proposed International Cricket Council (ICC) sanctions against the United States of America Cricket Association (USACA) for maladministration, but the situation was resolved the month before the tournament.

A feature of the championship was its low scoring, with only four innings above 200 being recorded from the ten matches played.
