Justiniano Borgoño Castañeda (5 September 1836 – 27 January 1921) was a Peruvian brigadier general and politician who served as the 29th President of Peru, an office he held for four months in 1894.

Borgoño quickly called for general elections, allowing Cáceres' reelection in August of that year.

[1] After the rebellion was defeated, Borgoño returned to Tulape and leased the property from his parents, which he administrated for twenty years.

[6] The battalion was assigned to safeguard La Punta to protect Peru from a possible landing by the invading Chilean Army, then transferred to the Morro Solar in Chorrillos.

On 13 January 1881, during the Battle of San Juan and Chorrillos, Borgoño, who had reached the rank of colonel, injured his right leg and was taken prisoner.

[8]Although Borgoño had promised not to take up arms following his release, he was appointed General Commander of La Libertad in July 1881, a position he held until the following June.

[1] Under General Miguel Iglesias, Borgoño led a division which fought in San Pablo on 13 July 1882, leading to a Peruvian victory.

That year, he was also named the General Commander and Prefect of Arequipa and served as the interim Minister of War and Navy until February 1885.

[3] From July 1885 to November 1885, as commander of the Army's 1st Division, Borgoño participated in battles and confrontations in Masma, Canta, Huaripampa, and Chicla, eventually leading to the capture of Lima in December of that year.

He was once again appointed Minister of War and Navy as soon as Cáceres took office as president on 4 June 1886;[11] he held this position until the following year.

[12][14] Prior the end of his first term as president, Morales Bermúdez contracted an illness and died suddenly on 1 April 1894.

[13] Within the first week as his period as "caretaker president",[14] Borgoño dissolved the Congress, claiming that it was illegitimate and did not represent Peruvian interests, and called for new general elections.

[14] After Piérola assumed the presidency, Borgoño left Peru and relocated to Argentina; there, he once again worked on agricultural ventures.

[22] A street in Miraflores, Lima, was renamed in his honor; Calle General Borgoño extends eleven blocks and is interrupted by the Huaca Pucllana.
