Royal Mail's director of external affairs and policy, David Gold, said: 'The superb writing and the warmth and idiosyncrasies of its characters made The Vicar of Dibley one of the most loved TV comedies of all time.
'We celebrate the series with new stamps revisiting some of the show's classic moments.'
The sitcom, created by Richard Curtis, was inspired by the Church of England's decision in 1993 to allow the ordination of women.
It traced the fortunes of French's character, Granger, after she is appointed as vicar in the fictional Oxfordshire village of Dibley, with episodes showing her learning to live and work alongside a colourful band of locals, including parish councillor Jim Trott (played by Trevor Peacock) and church verger Alice Tinker (Emma Chambers).
The Royal Mail set includes two second-class stamps, one showing Geraldine at the chaotic wedding ceremony of Hugo Horton (James Fleet) and Alice, and another of Geraldine forcing David Horton (Gary Waldhorn) to smile after hearing that Alice and Hugo are expecting a baby.
The moment where Geraldine jumps into a very deep puddle, and a recurring scene where she attempts to tell Alice a joke in the vestry over a cup of tea, are both depicted on first-class stamps.
Also included are £1 stamps of Frank Pickle (John Bluthal) and Owen Newitt (Roger Lloyd-Pack) performing in the Dibley Christmas show, while another shows Jim writing his characteristic response: 'No, no, no, no, no' - on a piece of paper to avoid waking Alice and Hugo's baby.
One of the best remembered scenes of the sitcom found Geraldine taking charge of a dance routine alongside Dame Darcey.
This moment, and a scene where Geraldine samples a sandwich made by Letitia Cropley (Liz Smith), are both featured on £2.80 stamps.
French's comical cleric tied the knot with handsome newcomer Harry Kennedy, played by Richard Armitage, in the final full-length episode on New Year's Day in 2007.
A handful of Comic Relief sketches and mini-episodes have appeared since the series officially ended, including three short 'sermons' broadcast during the Covid-19 pandemic.
