Wikimedia Foundation taps Bernadette Meehan as its new chief executive
SAN FRANCISCO: Bernadette Meehan will take the helm of the Wikimedia Foundation on January 20th 2026, stepping in as chief executive to steer the world’s largest free-knowledge movement through an era of rising regulatory scrutiny and fast-moving AI disruption. The Foundation announced the appointment on December 9th, pitching Meehan as a leader with the global instincts and political dexterity needed for Wikimedia’s next chapter.
Chair of the board of trustees Lorenzo Losa said Meehan’s collaborative, diplomacy-driven approach made her the right steward for a movement built on volunteer energy and global participation.
Meehan arrives with heavyweight foreign-policy credentials. She served as US ambassador to Chile from 2022 to 2025, leading a string of diplomatic wins—from passage of a bilateral tax treaty to a major subsea-cable project linking South America with Asia. Before that she was executive vice-president for global programmes at the Obama Foundation, crafting leadership networks across Africa, Asia-Pacific, Europe, Latin America and South Asia.
Her decade-plus career as a US foreign service officer included stints as special assistant to the president, spokesperson for the National Security Council, and postings in Colombia, Iraq and the UAE. Earlier, she cut her teeth in finance at J.P. Morgan Chase and Lehman Brothers.
Meehan said she was “thrilled” to join as Wikimedia marks 25 years of collaborative knowledge-building, adding that Wikimedia’s mission sits at the heart of more resilient, informed societies.
As chief executive, she will oversee global staff and work closely with thousands of volunteer editors and affiliates. Her priorities include product and technology upgrades, navigating AI-content challenges, strengthening ties with global communities and shoring up the Foundation’s financial resilience.
Meehan succeeds Maryana Iskander as Wikimedia’s sixth chief executive—and steps into the role just as the world’s most-used reference site gears up for its next quarter-century of keeping knowledge open, human and gloriously unruly.
