Park's office said Zuckerberg assured the South Korean leader that Facebook would continue to invest in the country, and he invited South Korean firms to jump on Facebook to reach global users.
Zuckerberg's visit is the latest in series of meetings between Park and high-profile U.S. technology pioneers. In April, Park met Microsoft Founder Bill Gates and Google CEO Larry Page in her office.
Park sees fostering startups and entrepreneurship crucial to raise South Korea's employment rate to 70 percent before the end of her five-year term.
Zuckerberg is meeting executives at Samsung Electronics Co. before leaving Seoul later Tuesday.
