Ijon Tichy is a fictional character who appears in several works of Stanisław Lem, including The Futurological Congress, Peace on Earth, Observation on the Spot, The Star Diaries and Memoirs of a Space Traveller (more stories from The Star Diaries, issued in English translation as a separate volume).

Tichy is a space explorer whose interplanetary experiences are chronicled in The Star Diaries. He also moves in scientific circles on Earth; he is invited to the Futurological Congress in Costa Rica and his endorsement and approval are sought by a number of researchers and inventors on the edge of their field, such as Doctor Diagoras who has developed an artificial intelligence which is independent of mankind, and Decantor who has invented an immortal soul.

Tichy himself is the narrator in all the stories in which he appears. Sometimes he is the main protagonist; sometimes he merely serves to introduce some other character who has a story to tell. He is unmarried, usually well-meaning, accident-prone, and commendably honest about his failures, which include (thanks to another unfortunate experience with time) the entire Universe as we know it.

Tichy is a town in northern Algeria.
