Mr. Popper's Penguins is a children's book written by Richard and Florence Atwater, with illustrations by Robert Lawson, originally published in 1938.

It tells the story of a poor house painter named Mr. Popper and his family, who live in the small town of Stillwater in the 1930s.

Mr. Popper is a house painter of modest means, living with his wife and two children (Bill and Janie) in the small town of Stillwater, Minnesota.

As both birds cannot fit into the icebox together, Mr. Popper opens the window to let in the cold winter air, creating a snow-covered habitat.

As this solution will not work in springtime, Mr. Popper has the main things moved upstairs and a freezing plant installed in the basement for the birds.

Common Sense Media wrote: "Vivid imagery, clever word plays, and funny characters that border on the absurd have made this book a popular choice for kids in classrooms and at home.

"[7] Mr. Popper's Penguins was named a Newbery Honor Book in 1939 and won the 1940 Young Reader's Choice Award.

A 20th Century Fox film based loosely on the book was released on June 17, 2011 and starred Jim Carrey as Mr. Popper.
