2019–20 CONCACAF Nations League B

The 2019–20 CONCACAF Nations League B was the second division of the 2019–20 edition of the CONCACAF Nations League, the inaugural season of the international football competition involving the men's national teams of the 41 member associations of CONCACAF.

Format
League B consisted of sixteen teams from qualifying which finished from 7th to 22nd. The league was split into four groups of four teams. The teams competed in a home-and-away, round-robin format over the course of the group phase, with matches played in the official FIFA match windows in September, October and November 2019. The four group winners were promoted to League A, while the four last-placed teams in each group were relegated to League C for the next edition of the tournament.

In September 2019, it was announced that the Nations League would also provide qualification for the 2021 CONCACAF Gold Cup. The winners of each of the four League B groups qualified for the Gold Cup, while the second-placed teams entered the first round of Gold Cup qualification.

Seeding
Teams were seeded into the pots of League B according to their position in the November 2018 CONCACAF Ranking Index.

The draw for the group phase took place at The Chelsea in Las Vegas, Nevada, United States on 27 March 2019, 22:00 EDT (19:00 local time, PDT).

Groups
The fixture list was confirmed by CONCACAF on 21 May 2019.
