Bolek and Lolek (Polish: Bolek i Lolek), also known in English as Benny and Lenny, Jym and Jam and Tim and Tom, are two Polish cartoon characters from the children's animated comedy television series by the same name.

The series is about two brothers and their fun (and sometimes silly) adventures which often involve spending a lot of time outdoors.

In English, the cartoon was distributed as Benny & Lenny, Jym and Jam and Tim & Tom.

In 1973, at the requests from female viewers, a girl character by the name of Tola was added; she lives in the forest and meets the brothers there.

During the period of the Polish People's Republic, Bolek and Lolek were reproduced in a large quantity of toys: action figures, movies, postcards, online arcades, puzzles, etc., which can be seen in the Museum of Dobranocki (bed-time stories) of the PRL.

In the U.S., some episodes were seen as part of Nickelodeon's Pinwheel from 1977 to 1990, In Canada, the show reran on the French-speaking TVJQ (now Vrak) in the 1980s.
