Union Hill Middle School is a public middle school serving students in seventh and eighth grades from Union City in Hudson County, New Jersey, United States, operating as one of two middle schools of the Union City Board of Education, an Abbott District. The school was built in -- and named for -- what was formerly Union Hill, New Jersey, a municipality which merged with West Hoboken in 1925 to form Union City. Until 2008, the Union Hill school was one of the city's two high schools, with the current Emerson Middle School the other.
