Herry Monster is a Sesame Street monster who doesn't know his own strength. Herry first appeared in season 2, effectively replacing the Beautiful Day Monster in the Sesame monster troupe. In his first appearances, Herry's nose was covered with light blue fur as well. During the second season, he gained a non-furry blue nose, which was replaced by his signature purple nose in 1971. The Herry puppet was also used for the original Big Bad Wolf.

Herry was often seen in Muppet & Kid Moments, relating to real children, and in later seasons appeared in the recurring sketch Monsters in Day Care. Herry has also participated in many of Prairie Dawn's pageants, as well as appearing in such Monsterpiece Theater segments as "Chariots of Fur," "Guys and Dolls." and "ABCD Blue." Herry hosted the Fuzzy Awards in the video Monster Hits! and he was an anchorman in We All Sing Together.

His family consists of a mother, a father, a grandmother, a niece in Episode 1033, a sister named Herriet in Episode 1073, and a young sister named Flossie seen in several storybooks. He also has a doll named Hercules who has been seen with him in "Guys and Dolls," "A Song for Two," "Moonshine" (a song with Zoe where they sing about their dollies), and when he slept over at Gabi's in a 1998 episode.

Herry is known for appearing in illustrations (and some merchandise and on the Sesame Street Live productions) wearing pants. Usually they would be white with pink stripes, but the costume used in Sesame Street Live would give Herry light blue pants, and illustrator Tom Cooke usually drew Herry in purple pants with orange spots. He hasn't been seen wearing pants elsewhere, and the few times he has been shown below the waist, he is unclothed, like most monsters.

Another attribute of the character from illustrated merchandise is that Herry was sometimes depicted as the proprietor of a barber shop on Sesame Street. Usually wearing a short-sleeved barber's shirt and his customary (for illustrations) striped pants, Herry could be seen working at Herry's Barber Shop in the 1983 book People in Your Neighborhood, a puzzle from Sony, the 1986 Rub n' Play transfer set, and the Busy Builders Playtown.

Like Cookie Monster, in rare instances Herry has taken to eating traditionally inedible objects, such as a bicycle, a restaurant table, the letter in M-M-M Monster Meal, but usually in the company of his googly-eyed friend.

Though Herry still makes occasional appearances in new episodes, he seldom plays a prominent role. He can be seen in The Street We Live On and made a cameo in Episode 4206 (puppeteered by Marty Robinson), in line at Hooper's Store.
