Pedro Francisco Callisaya Aro (born 10 October 1966) is a Bolivian academic, constitutional lawyer, and jurist serving as the sixth ombudsman of Bolivia since 2022.

Callisaya developed his career in academic circles, completing multiple graduate and postgraduate courses in the fields of constitutional law and human rights.

Given the fraught manner in which he was elected, Callisaya's tenure as ombudsman faced the task of recovering the office's credibility as an impartial institution after years of increased politicization.

[1][2] After that, he undertook postgraduate studies abroad, attending the University of Alcalá in Madrid, Spain, where he completed courses in democracy, rule of law, and human rights.

Nonetheless, he remained far short of the necessary two-thirds to attain the position,[9] with even the majority Movement for Socialism (MAS) initially divided between support for him and rival Porfirio Machado.

[15] This self-critical approach was met with hopeful optimism from some analysts, with activist Franco Albarracín commenting that Callisaya's statements were a "positive sign" that the new ombudsman would seek to be an impartial defender of human rights.
