It was Honduras' third title in the competition's history, adding to its 1990 and 1994 triumphs.
In the early going, the Hondurans were content to sit back, conceding territory and possession time to the Ticos.
With its first shot of the game, though, Honduras struck for the winner through Real Espana's Brayan Rochez just before the interval. His right-footed effort from long distance, off a pass from Jose Escalante, dodged the outstretched arms of Costa Rican goalkeeper Jairo Monge.
Rochez, who also scored single tallies against Guatemala and El Salvador, nearly doubled the Catrachos' advantage in the 75th minute, but Monge was up to the task.
In an attempt to find an equalizer, Costa Rica -- which had won each of its previous four tournament games - inserted Rodrigo Garita into the game with 25 minutes remaining. Despite the talented offensive midfielder's presence, the home side fell short.
In the bronze medal match, El Salvador defeated Guatemala 2-1 on a late goal by Giovanni Zavaleta.
