The Turtle Lair, or "casa", appears in the Teenage Mutant Ninja Turtles (Rizzoli) comic series. It is the place beneath New York City where the Turtles live, being home to Leonardo, Donatello, Raffaello, Michelangelo and Splinter.
The Lair in these comics is similar to that which appeared in the 1987 TV series. It contains several rooms including:
- A large living area used as a common room.
- A kitchen.
- Tunnel shaped rooms used as bedrooms by the Turtles.
