Eastern High School is a public high school in Lansing, Michigan as part of the Lansing School District. Eastern International Baccalaureate Magnet High School is the only high school in mid-Michigan authorized to offer students the opportunity to earn a prestigious International Baccalaureate Diploma. Eastern also has the second largest alumni association in the United States. It is located on the city's east-side on Pennsylvania Avenue, one block north of Michigan Avenue. The building was connected with former Pattengill Middle School next to Sparrow Hospital. In 2007, Sparrow purchased the Pattengill property to create a parking lot. With the deconstruction of Pattengill Middle School, Lansing Eastern became the oldest operational school in the Lansing School District. It opened in 1928 as the second high school in the city. The athletic teams were named Quakers because the school was located on Pennsylvania Avenue and a Society of Friends (Quaker) meeting house was located across the street.
