Maradona, who most recently managed UAE second-division side Fujairah, will be taking over football operations.
"Yes, Diego is with us!" "Diego Maradona will be in charge of the team's strategic development and will interact with all its structural subdivisions, including the Junior Academy of the football club", the press service noted.
Dinamo, based in the south-west of Belarus, are now in eighth position in the country's Premier League.
Argentine legend Maradona, a former World Cup victor recognised as one of the all-time greats, last month stepped down as coach of United Arab Emirates second division club Al-Fujairah.
With Fujairah he left the club after failing to secure promotion to the UAE's top flight in April.
"I am president of the club, Dynamo Brest", Maradona said in an Instagram post on Tuesday, reports EFE news agency.
Brest, who won the Belarusian Cup a year ago and its Super Cup in March, said Maradona will be officially introduced as chairman at Emirates Palace hotel in Abu Dhabi.
"Thanks for the trust and for thinking of me", he added.
The 57-year-old will take charge of Dynamo, who are eighth in their league, after the conclusion of this year's World Cup in Russian Federation.
