The short answer
Carlos is the Spanish and Portuguese form of Charles, according to Behind the Name, and belongs to the large family of names descended from the Germanic root that entry records as karil/karl; the gloss of that root is documented on the Charles entry rather than here.

It is a masculine name with diminutives Carlitos and Carlito in Spanish and Carlinhos in Portuguese, and feminine forms Carla and Carolina. In the United States it ranked #150 for boys in 2025.
