"I am excited to be heading back to the Stags for the Super Smash campaign. I thoroughly enjoyed my time last year, so it was an easy decision to return again this year," Jayawardene said.
"The Stags have a great culture, and a team full of young, but experienced cricketers. I hope that I can make a difference for the team on the field, but off the field too."
Jayawardene will join the Stags for either round two or three of the Super Smash. This is largely dependent on where his team, the Dhaka Dynamites, finish in the Bangladesh Premier League.
Central Districts Cricket Association chief executive, Pete de Wet, is thrilled to see a player of Jayawardene's quality in the Stags T20 side.
"Mahela brings a special quality with him, and he adds to what is already a very strong squad. I would urge fans to get their tickets and come to the stadium to watch Mahela, and the Stags in action during this year's Super Smash," de Wet said.
