St Paul's Cathedral has set up an online memorial page for people all across the country to add to.
Remember Me 2020 allows people to submit a photo, name and short message about someone who has died in the UK.
People of any faith or none can contribute to it and it has got the backing of Prince Charles and leaders of other faiths.
It will be open for entries for as long as needed.
To launch the project, the choristers of St Paul’s Cathedral have recorded a piece of music, Mendelssohn’s Lift Thine Eyes, part of Psalm 121, to serve as an anthem for the book of remembrance.
The Dean of St Paul’s Cathedral, the Very Reverend David Ison, said: "For centuries, St Paul's Cathedral has been a place to remember the personal and national impact of great tragedies, from the losses of war to the devastation of the Grenfell Tower fire. We have heard so many sad stories of those affected by the pandemic, and all our thoughts and prayers are with them. Every person is valued and worthy of remembrance.
"We are all experiencing the devastating impacts of COVID-19 across the country and beyond. Remember Me is an opportunity to mourn every person we have lost to the effects of this terrible disease, an encouragement to offer compassion and support to those left behind, and an ongoing recognition of the impact of the pandemic on the UK."
It is hope that the online memorial will become a physical one in the building one day.
