The year will start with Genius of Gerry Anderson stamps, marking the 50th anniversary of his work, which includes Thunderbirds, Stingray and Joe 90.
Musicals will feature on eight new stamps in February, while in March they will reflect the tales of King Arthur and his court magician Merlin.
The 50th anniversary of environmental group WWF will also feature in March, with portraits of 10 animals on stamps, including the African elephant, the Siberian tiger and the African Wild Dog.
Stamps in April will depict Shakespeare plays, showing theatres where the Royal Shakespeare Company has performed in Stratford-upon-Avon through the years.
Philip Parker, Royal Mail stamps spokesman, said: ''This is by far the most exciting start to a year for Royal Mail stamps. The year blasts off with Thunderbirds, Stingray and the amazing TV series of Gerry Anderson, and the excitement doesn't stop there.
''There's something for everyone in the first half of 2011, with musicals, magical realms and WWF just some of the themes dropping on the doormats across millions of homes in the UK and across the world.''
