The Pará-class destroyers were a class of 10 destroyers built for the Brazilian Navy between 1908 and 1910 by Yarrow in the Scotstoun district of Glasgow, Scotland. All were named after states of Brazil. The class closely resembled the British River-class destroyers. All ten ships were ordered under the 1907 Naval Programme and exceeded the design speed during sea trials, the best being Parana. The class proved very maneuverable with a turning circle of 375 yards at full speed. The class served in both World War I and World War II.

Design
The Pará class was designed for a crew of 104 men, powered by double shaft four cylinder VTE engines with two coal-fired Yarrow boilers which produced 8,000 shaft horsepower (6,000 kW). With a capacity of 140 tons of coal their range was 3,700 nautical miles (6,900 km; 4,300 mi) at 14 knots (26 km/h; 16 mph). They were armed with two 4 in (102 mm) guns, four 3-pounder guns, and two 18 in (460 mm) torpedo tubes.
All units exceeded their 27 knots (50 km/h; 31 mph) design speed; the best trial speed was Parana, at 28.736 knots (53.219 km/h; 33.069 mph). The ships were divided into ten watertight compartments by bulkheads from the outer bottom plating to the upper deck. The class proved to be very maneuverable; the diameter of the turning circle was 375 yd (343 m; 1,125 ft) at full speed and 340 yd (310 m; 1,020 ft) at two-thirds speed.
Ships
