The 2020 men's Muratti will take place in on Saturday 16th May, and the women's final is back for the first time since 2016.
The Jersey and Guernsey FAs have confirmed the fixtures for next year's football island-insular.
There will be three consecutive days of action at Springfield Stadium.
It will start on the Friday evening with an over 50s charity game in aid of Cheshire Home. Last year Southampton legend Matt Le Tissier took part and the drew a bumper crowd.
The trophy holders Jersey will then host the winners of the Guernsey v Alderney semi final in the men's final with a 3pm kick-off on the Saturday.
The JFA says it will be an 'all-ticket' final with no tickets available on the day and no fans viewing through fencing following feedback from 2018.
Condor will operate an extra sailing from Guernsey to Jersey for match-day.
The women's Muratti returns after a four year gap and will be played on Sunday 17th May (2pm)
There will also be disability and walking football matches.
“With the 75th anniversary of the Liberation of the Channel Islands, May 2020 will be a special time for our islands and we’ll certainly be reflecting that sense of celebration with a packed schedule of inter- insular competition, which will include; men, women, disability and walking footballers.” - Jean-Luc Desbois, JFA CEO
Guernsey FA Director James Falla added: “The 2020 Muratti is looking to be an action-packed weekend and we are greatly looking forward to it. Obviously at the senior men’s level we must face what will undoubtedly be a tough match against Alderney in the semi-final, and so we take nothing for granted.
“We are all delighted to see the return of the Women’s Muratti in 2020. The introduction of the CI Women’s League, with the invaluable support of our partners at Condor Ferries, has been a major development for the women’s game in Guernsey, and the growth in player numbers and interest we have seen so far is exciting.
“The return of the Muratti is an important step forward for the growth of the women’s game in the island, as we still maintain our focus on the development of our squad for the 2021 NatWest Island Games in Guernsey and beyond.”
