Eduardo Alejandro Roca (15 December 1921 – 17 May 2019) was an Argentine lawyer, academic and career diplomat. Over several decades he represented Argentina in high‑level posts abroad and at international organizations. His public life combined legal practice, university teaching and formal diplomatic assignments during some of Argentina's most turbulent political episodes.

Early life and family background

Roca was born in Buenos Aires, into a family with deep roots in Argentine public life; he was a grand‑nephew of President Julio Argentino Roca. He trained as a lawyer and later combined legal work with scholarly activities, maintaining a profile as both a practitioner and a public intellectual within Argentina's legal community.

Diplomatic career

Roca held several important diplomatic posts. He was appointed as Ambassador to the United States and served in Washington between 1968 and 1970, representing Argentine interests to the government and public of the United States. Later he was named Argentina's permanent representative to the United Nations, a post of particular prominence during international crises.

During the 1982 conflict over the Falkland Islands, Roca represented Argentina's positions at the United Nations, engaging with diplomatic counterparts and international institutions while the dispute drew intense global attention. His role required balancing legal arguments, national policy and multilateral diplomacy at a time of acute international scrutiny.

Beyond formal postings, Roca was known for his contributions to legal education and public debate in Argentina. He combined experience in government with an interest in constitutional and international law, and he periodically participated in academic forums and publications addressing Argentina's legal and diplomatic challenges.

Legacy: Roca's long life spanned much of the twentieth century and the start of the twenty‑first; he remained a figure associated with mid‑century Argentine diplomacy. He died in Buenos Aires on 17 May 2019 at the age of 97. His career is often cited in discussions of Argentina's foreign relations during the 1960s through the 1980s and in studies of the country's legal and diplomatic institutions.
