The benches were commissioned with a suicide prevention charity - the 'Campaign Against Living Miserably' (Calm) and feature QR codes leading to online resources and a message of support.
After Life's third and final series was released on Friday January 14th, starring Gervais as local journalist Tony, a man plunged into intense grief following the death of his wife.
In the show, Tony is often seen sitting on a bench at his local churchyard as he reflects on his loss.
Netflix has donated 25 benches in total to local councils around the UK as part of a mental health initiative celebrating the launch of the new series.
The benches, which have been installed in Cardiff's Victoria Park and Parc Cefn Onn, are inscribed with a quote from the third series: "Hope is Everything."
Cllr Peter Bradbury, Cabinet Member for Culture and Leisure said: "I'm delighted that Victoria Park and Parc Cefn Onn will benefit from these benches.
"They're the perfect complement to Cardiff Council's three purple ‘Happy to Chat' benches in Roath Park, Hailey Park and Bute Park as they've all been installed to help tackle loneliness or offer the chance for people to talk to someone else, regardless of their circumstances.
"As the weather continues to improve and restrictions continue to ease, the Benches of Hope and Happy to Chat benches in these parks will allow people to meet others, feel connected with their community and help to combat isolation."
Gervais, who is the writer, director and executive producer of the show said: "We hope the benches will create a lasting legacy for After Life, as well as become a place for people to visit, and we are thrilled to be associated with Calm and the great work they do."
Calm chief executive Simon Gunning said: "Park benches provide opportunities to reflect, talk to someone, sit shoulder to shoulder with someone and get things off your chest.
"That is why we're delighted to team up with Netflix to put benches in parks across the country - inscribed with that crucial line from the show, 'Hope is everything' - to help people have those conversations and to show it's normal to have those feelings."
After Life was Netflix's second most popular series of 2019, behind fantasy drama The Witcher.
