JumpStart Adventures 4th Grade: Haunted Island is a JumpStart game that was made by Knowledge Adventure on December 2, 1996. It was later re-released on November 24, 1997 with Map Scroll and Ms. Grunkle's Hat level indicator added. As the title suggests, the game is intended to teach a fourth grade curriculum. It was later replaced by JumpStart Adventures 4th Grade: Sapphire Falls in 1999. In its original release, it contained KnowledgeLand as a bonus disc.

The user is a fourth-grade student, who, fortunately, missed the day of school when the class's substitute teacher was a witch named Ms. Grunkle.

After signing in at the schoolhouse, the user is transported to Haunted Island. With the aid of a large purple bat named Flap and a fortune teller named Madame Pomreeda, the user must rescue the thirteen lost classmates by collecting the students' "most prized possessions" from the island's educational activities. After these possessions, which reveal elements of the kid's personality, are collected, Madame Pomreeda transforms the classmate back with a poem that tells the monster to go away and the child to return.
