Kjeld Kirk Kristiansen is a Danish businessman, the billionaire former CEO and controlling owner of The LEGO Group, the global toy giant. His colossal wealth is generational, tied to the industrial empire founded by his grandfather, Ole Kirk Christiansen, in 1932 (who started making wooden toys).

Kristiansen is the third generation of the founding family and the son of Godtfred Kirk Christiansen (who named the iconic LEGO brick). His career is defined by generational stewardship and creative revitalization of the brand. He holds a degree in Economics from the Aarhus School of Business and an MBA from IMD, Lausanne.
