The 2018 CONCACAF Women's Championship was the 10th edition of the CONCACAF Women's Championship (also known as the CONCACAF Women's Gold Cup or the CONCACAF Women's World Cup Qualifying Tournament), the quadrennial international football championship organised by CONCACAF for the women's national teams of the North, Central American and Caribbean region. Eight teams played in the tournament, which took place from 4–17 October in the United States.
The United States were the defending champions of the competition. They successfully defended their title as hosts, winning the final 2–0 against Canada for their 8th CONCACAF Women's Championship title.
The draw for the final tournament was held on 4 September 2018, 10:00 EDT (UTC−4), at the Univision Studios in Miami. The eight teams were drawn into two groups of four teams. They were seeded into four pots. Pot 1 contained the United States, seeded in Group A, and Canada, seeded in Group B. The remaining six teams were allocated to Pots 2–4 based on the CONCACAF Women's Rankings. The two teams from UNCAF could not be drawn into the same group.
The provisional 35-player roster (4 must be goalkeepers) for each team was announced by CONCACAF on 10 September 2018. The final 20-player roster (2 must be goalkeepers) for each team was announced by CONCACAF on 26 September 2018. After the final 20-player roster was submitted, only injury-related changes would be submitted until 24 hours before each team's first match.
In the semi-finals, if the match was level at the end of 90 minutes, no extra time would be played and the match would be decided by a penalty shoot-out. In the third place match and final, if the match was level at the end of 90 minutes, extra time would be played, and if still tied after extra time, the match would be decided by a penalty shoot-out (Regulations Article 12.14).
