Monster in the House is a 2007 Sesame Street Lift-the-Flap book. The book is an altered reprint of the 1995 book Is There a Monster in the House? Elmo has been added to the cover and several inside spreads by illustrator Tom Leigh, who is credited as "Contributing Illustrator".

In the book, Grover explores a haunted house, frightened by the bumps and squeaks that he hears around every corner. Fortunately, the source of the noises turn out not to be scary after all -- they're just monsters! At the end of the book, Grover and the monsters are "one happy family", dancing in the parlor.
