The group's Seasoned Events brand will deliver catering to over 800 people each day in seven locations at the five-day annual event.
Charles Beer, chief executive, Crown Group, said: "We are really pleased to be partnering Leander for this event once again.
"Leander Club has an unrivalled reputation, not only in the UK but internationally, so we are absolutely delighted to be able to support them at such a prestigious event."
Paul Budd OBE, general manager at Leander Club, said: "Unlike many classic summer events, Leander's hospitality needs are based squarely on a Club ethos and the majority of our members have been attending Regatta annually for many years.
"Our members' expectations are both demanding and high, and the Crown Group has demonstrated the skill and understanding to meet these expectations and provide the little touches that single them out from the run of the mill event providers."
Seasoned Events' sister enterprise Piggotts, which also falls under the Crown Group umbrella, has been contracted to provide two grand marquee complexes.
