Gamboa is a small town in the Republic of Panama. It was one of a handful of permanent Canal Zone townships, built to house employees of the Panama Canal and their dependents. The name Gamboa is the name of a tree of the quince family.
Gamboa is located on a sharp bend of the Chagres River at the point which feeds Lake Gatun. Just south of Gamboa, Lake Gatun and the Chagres meet the Gaillard Cut where the Canal cuts through the Continental Divide. Thus, though Gamboa is closer to the Pacific side of Panama, its watershed is on the Atlantic side.
