Luis María del Corazón de Jesús Dionisio Argaña Ferraro (October 3, 1932 in
Asunción – March 23, 1999 in
Asunción) was a prominent
Paraguayan politician and Supreme Court judge. He was an influential member of the
Colorado Party and rose to the Vice-Presidency in 1998, but was assassinated in March 1999 at a time when it appeared likely that he would inherit the presidency from
Raúl Cubas, who was on the verge of being impeached. The incident and its aftermath is known in Paraguay as "Marzo Paraguayo" (the Paraguayan March). An airport in Paraguay,
Dr. Luis María Argaña International Airport, is named for him.
