The former Sri Lankan international is the first non-British President of MCC and will hold the post for one year.
His nomination was announced by the outgoing President, Anthony Wreford, at the MCC Annual General Meeting at Lord’s in May this year.
Kumar Sangakkara said: “I am thrilled to hold the prestigious position of MCC President and I look forward to working hard with the MCC to build on this incredible year of cricket.
“We have an opportunity to convert more supporters to the game we love and educate them about the fantastic work MCC does locally, nationally and globally for cricket and those communities.”
Sangakkara has a long association with MCC. He played against the Club in 2002, opening the batting for the touring Sri Lankans in a first-class match at Queen’s Park, Chesterfield.
