Lenny Turteltaub is an anthropomorphic turtle and big-shot Hollywoo producer and a recurring character throughout BoJack Horseman.
Lenny is in talks with Princess Carolyn to produce a movie about the last days of Eva Braun. However, when Vanessa Gekko steals the project out from under her, Princess Carolyn tanks that project and pitches Mr. Peanutbutter’s Hollywoo Heist, to Lenny instead. Lenny agrees to pitch the idea to Quentin Tarantulino and the film soon begins production, starring BoJack Horseman as the lead. However, Mr. Peanutbutter's Hollywoo Heist never wraps up filming, as the format changes multiple times.
Lenny is a dry-witted, monotone producer. His age is intended to be in his 50's but he said to have known a young Buster Keaton, so he has had to be a lot older in order for that to be true.
Being a producer, his main point in making movies is to make a lot of money for the business and get recognition, but he is not a careless producer who doesn't put any thought into anything in the film's story.

- Though Lenny's name is often misspelled as Lennie, show creater Raphael Bob-Waksberg has confirmed the correct spelling is Lenny Turteltaub.
- The name could be a riff on Jon Turteltaub, an American film director and producer.
