The service will be broadcast live on the D-Day Story Facebook page at 11am on Saturday, 6 June, and will be led by Father Bob White, from St Mary's Church, Portsea and Chaplain to the Royal British Legion.
This year's commemorations will look very different to normal with people unable to get together to remember the event but efforts are still being made to mark the anniversary and keep the story of D-Day alive.
D-Day Story museum is marking the 76th anniversary by sharing a range of stories from on its Facebook page on 5 and 6 June, which will stay there to see for anyone who can't join in at the time.
The museum will be live on Facebook on 5th June at 10am talking about past D-Day anniversaries and the meaning of commemoration, illustrated by objects from its collection.
On 6 June the Facebook page will be sharing stories from its volunteers on the importance of remembering D-Day.
And the museum is asking the public to share their pictures, memories and images from last year's week long D-Day 75 commemorative and celebratory events which saw Portsmouth take centre stage and host world leaders, armed forces and most notably D-Day heroes.
This year as veterans can't get together to remember their comrades the aim is to collectively share memories of D-Day 75 until they can once again be honoured in person.
Cllr Steve Pitt, Deputy Leader, Portsmouth City Council said: "As we reflect on our history during these poignant times, it's more important than ever to remember the stories of those who gave us the freedom that we treasure. We hope people will join us in marking D-Day 76 by sharing their images of D-Day 75 as we think about how different our commemorations in Portsmouth are this year - but how vital it is to keep our veterans' D-Day stories alive."
The D-Day Landings were one of the pivotal moments in the Second World War - which led to the ceasing of hostilities - VE Day - less than a year later. Portsmouth was the centre of the staging areas for D-Day and one of the main embarkation points for the troops, who were assembled in camps in and around the city.
D-Day had a major impact on civilians in the city. Many local people befriended the Allied servicemen and they were the last to see the troops before they departed for Normandy.
Portsmouth's role in Operation Overlord continued long after D-Day. Men, vehicles and supply continued to pass through the embarkation areas for months afterwards. Wounded men were evacuated to Portsmouth and treated in hospitals some of those who died are buried in local cemeteries, and German prisoners of war disembarked here.
The D-Day Story museum captures these accounts and perspectives so that future generations understand and value the immense human cost.
