ARA Paraná was a steam and sail corvette built in United Kingdom in 1873 which served as a gunboat with the Argentine Navy between 1874 and 1899. It was decommissioned in 1900, converted to a transport and renamed Piedrabuena.
Paraná was a steam corvette rigged as a barque, with a steel hull covered in wood planks. She was powered by a 475 HP compound steam engine with two cylindrical boilers, driving a 2-paddle Bevis-type propeller. It could reach a speed of 11 knots (13 mph; 20 km/h) under sail and steam, or 10 knots (12 mph; 19 km/h) under steam only. 
Her main battery, as built, was composed of four Vavasseur mounted 7 in (177.8 mm) guns, mounted one at the front of the funnel, another behind it, and one per side.  As refitted in 1879, it included one 150 mm (5.9 in) (bow) and two 90 mm (3.5 in) (one per side) Armstrong guns. [n 2]
Paraná was ordered in 1872 as part of the so-called "Sarmiento’s Squadron", authorized by the Naval Law of 1872 to enhance the Argentine Navy after its performance in the Paraguayan War. Construction was contracted at a cost of £ 32,000 to the shipyard of Laird Brothers, at Birkenhead; together with her sister ship Uruguay. 
She was ferried to Argentina by a British crew, departing Birkenhead in April 1874 and arriving in Buenos Aires at the end of that month; being commissioned into the Argentine Navy on 2 May 1874. Her first commander was Sargento Mayor de Marina Ceferino Ramírez, who was removed from its command when the crew joins the September 1874 Revolution. After the failure of the revolution, Paraná was surrendered in the Uruguayan port of Maldonado, and returned to Argentina in late November 1874.  
Between 1876 and 1877 Paraná is assigned to Asunción del Paraguay, commanded by Captain Augusto Lasserre. From 1878 to 1884 she sails several times to the Patagonia, with a trip to Río de Janeiro in July-December 1882. In 1879 she is refurbished, including changing her armament. Between April and November 1884 she participates in the Argentine expedition to the South Atlantic to implement the Boundary Treaty of 1881, which concluded with the possession of Ushuaia on 12 October. She returned to Buenos Aires in late November 1884. 
From 1885 to 1889 she performs various tasks in the Paraná, Uruguay and de la Plata rivers, including hydrographic survey.  In 1894 she is repaired and modernized, including replacement of the boilers. During 1895, 1897 and 1898 is assigned to transport duties; and in 1899 is disarmed. In 1900 she is transformed to transport ship, reclassified, and renamed Piedrabuena.
