Jackson Township is one of twelve townships in Porter County, Indiana. As of the 2010 census, its population was 5,328.[4]
Jackson Township was organized in 1836, and most likely named after President Andrew Jackson, although, after that name became controversial in the 1840s, a latter (1883) account says it was named for Lemuel Jackson, a pioneer settler.[5]
There are no incorporated communities in the township.[6] However, the extreme southeastern portion of Chesterton does extend down to the northeastern portion of Jackson Township.
Jackson Township is served by the Duneland School Corporation. Their high school is Chesterton High School, located in Chesterton (Westchester Township) to the northwest.
