Mole (Czech: Krtek, Krteček) is an animated character in a series of cartoons created by Czech animator Zdeněk Miler. The premiere of the first short film with Mole took place at the Venice Film Festival in 1957. Since its inception, the cartoon has gained enormous popularity in many Central European countries, as well as India, China, Kazakhstan, Croatia, Finland, Russia, Ukraine, Belarus, Iran, Iraq, and Japan.

Krtek was first seen in 1956 in Prague, when Miler wanted to create a children's cartoon about how flax is processed. He wanted a strong Disney influence to the cartoon by choosing an animal for the leading role, and decided to pick a mole after stumbling over a molehill during a walk. The first film, called "Jak krtek ke kalhotkám přišel" ("How the mole got his trousers"), had its premiere at the Venice Film Festival in 1957, where it was awarded two Golden Lions. Production for further episodes started in 1963 and since then, around 50 episodes have been created.
The first episode of the cartoon was narrated, but Miler wanted the cartoon to be understood in every country of the world, so he decided to use his daughters as voice actors, reducing the speech to short non-figurative exclamations in order to express the mole's feelings and world perception. Miler's daughters also became the bottleneck of the creation process as they were the ones who got to see the whole film first, thus Miler was able to decide whether the message of the movie was able to get to children or not.
It took me a long time to realize it, but when I draw Krtek, I was drawing myself. — Zdeněk Miler
In the United Kingdom, the cartoons were transmitted by the BBC with English narration by Colin Jeavons.
