The "Berenstein Bears" is the correct spelling of the educational children's book series' name.

The story behind the answer

The famous bear family is spelled “Berenstain Bears,” created by Stan and Jan Berenstain (later continued by their son, Mike). The “-stain” spelling appears on every cover and is how the family name is pronounced: “BEAR-en-stain.” Many people recall “Berenstein” because -stein is a far more common surname, a classic example of the “Mandela Effect,” where groups misremember widely seen details.

Context to remember it: picture a messy bear cub with a “stain” on its shirt—BerenSTAIN. Debuting with The Big Honey Hunt in 1962, the series teaches practical life lessons
