Iris Balbina Fontbona González is a Chilean billionaire businesswoman, the widow of Andrónico Luksic Abaroa (d. 2005), and the richest person in Chile. Her colossal wealth is rooted in the Luksic Group, a massive industrial and financial conglomerate spanning mining (Antofagasta PLC), banking (Banco de Chile), beverages (CCU), and shipping (CSAV).

Fontbona was born in Antofagasta, Chile, in 1944. She married Andrónico Luksic Abaroa at age 20. Her career is defined by generational stewardship and fiduciary oversight of the complex family empire. After her husband's death from cancer in 2005, she and her three sons (and her stepson) inherited and managed the vast holdings.

• Antofagasta PLC (Controlling Shareholder): The core industrial asset, a global leader in copper mining (listed on the London Stock Exchange).
• Quiñenco (Majority Owner): The publicly traded holding company controlling Banco de Chile (banking), CCU (largest brewer), and CSAV (shipping).
• Stewardship Role: All major business decisions impacting the core company require her approval.
• Philanthropic Focus: She is famous for record-breaking donations to the Chilean Telethon.

Iris Fontbona's role is primarily one of guiding the strategic direction of the Luksic Group, which is run by her sons (e.g., Jean-Paul Luksic manages Antofagasta). Her structural strength lies in her veto power—major business decisions require her approval, ensuring family control over the entire conglomerate.

She aggressively consolidated some assets, notably acquiring a 70 percent stake in the Chilean television station, Canal 13, shortly after her husband's death. The family is a major global force in shipping (CSAV is the world's 16th largest shipping company). Her immense wealth is secured by the long-term, stable returns generated by the global copper market and her diversified holdings in Latin American finance and industry.

Iris Fontbona is a major global philanthropist. Her structural social impact is tied to Antofagasta's role as a massive industrial employer and foundational supplier of copper (a key global commodity). Her company's holdings in Banco de Chile are essential to the nation's financial stability.

Her personal philanthropy is immense and visible: she is famous for her record-breaking donations to the Chilean Telethon, contributing billions of Chilean pesos to aid children with disabilities. She also owns luxury hotel chains and real estate globally.

Iris Fontbona maintains the discreet, composed style of a Chilean matriarch. Her attire is consistently high-quality and elegant, favoring tailored conservative clothing. Her aesthetic reflects her stability and profound financial authority, preferring a low public profile despite her immense wealth.

Residing in Vitacura, Santiago, Chile (with other residences in London and Liechtenstein), her luxury is the immense security and financial reward derived from her multi-billion dollar fortune. Her life is dedicated to the stewardship of her family's legacy, managing the global mining and financial empire.
