A consortium led by American investor Boehly completed the takeover of the Blues last month.
He takes up the role of chairman after it was announced Bruce Buck will step down after 19 years.
Chelsea also confirmed the departure of director Marina Granovskaia, with Boehly taking over the role until a permanent replacement is appointed.
But Granovskaia will “remain available” to the club for the duration of the summer transfer window to help with the transition.
“As custodians of Chelsea FC, we now begin executing our long-term vision and plan for the club, creating an outstanding experience for its passionate, loyal fans and continuing to challenge for top honours in line with Chelsea FC’s decorated history,” said Boehly.
“Working together, side-by-side, we are firmly committed to winning, both on and off the pitch. For us, that effort has begun.”
