Dom Carlos I, from 1910 NRP Almirante Reis, was a Portuguese Navy cruiser of the early 20th century, the only ship of its type. It represented a typical protected cruiser design of the British Armstrong shipyard in Elswick of the turn-of-the-century period. Launched in 1898, it entered service the following year. In the course of its service, it performed representative duties and took part in the revolution of October 5, 1910. During World War I, it was withdrawn from active service due to wear on its boilers, and was struck from the fleet list in 1925. It was the largest ship of the Portuguese Navy of its time.

The ship's displacement was 4,186 tons. The main armament consisted of four 152 mm caliber cannons and eight 120 mm caliber guns. It was powered by steam engines, allowing it to develop a speed of 22 knots (41 km/h; 25 mph).
