Superior Charter Township is a charter township of Washtenaw County in the U.S. state of Michigan. The population was 14,832 at the 2020 census.

• Dixboro is an unincorporated community located within the township at 42°18′44″N 83°39′22″W / 42.31222°N 83.65611°W / 42.31222; -83.65611. Dixboro was settled as early as 1825 by John Dix and was platted in 1826 by A. B. Rowe. The name was first recorded in 1828 at a time when the area was still administratively part of Wayne County until Washtenaw County was created in 1829. A post office opened under the name Dixborough, which was named after John Dix, on December 6, 1825. The post office closed on September 25, 1850. The post office was then restored on two separate occasions from July 11, 1861 until January 20, 1863 and again from May 26, 1890 until it ultimately closed on June 15, 1905. Even after John Dix sold his properties and moved to Texas in 1833, the community was growing faster than the nearby community of Ann Arbor. However, the railroads bypassed Dixboro in favor of Ann Arbor, and the community slowly dwindled. The oldest structure within the community is the Dixboro General Store, which was built in 1840.
• Frain Lake is an unincorporated community located within the township at 42°19′44″N 83°37′01″W / 42.32889°N 83.61694°W / 42.32889; -83.61694. It is along Plymouth Road near the small lake of the same name. The name of the lake and community are sometimes spelled as Frains Lake or Frain's Lake. The settlement began in 1835 when Michael Frain from New York came to the area and purchased land in Superior Township.
• Geer is a historic settlement that was named after early settler William Geer, who became the first postmaster when the Geer post office opened on June 13, 1890. The post office closed on August 31, 1900. A one-room schoolhouse, now named the Geer School since he also served as an elected school director, remains standing and is now a county-designated historic site. It was constructed in 1880 to replace an earlier 1829 log structure, and it was an active educational facility until it closed in 1982. It is currently owned by Plymouth-Canton Community Schools and used as a historic exhibit.

Robert Fleming bought the first plot of land here in the Michigan Territory in 1823. A sawmill was built in 1826, and the Bank of Superior was established in the community in 1838.

• Harris Fletcher (1892–1979), academic, author, and leading authority on John Milton

In 1846, Isaac Van Woert swore in an affidavit to a justice of the peace in Ann Arbor that he had been visited by the ghost of Martha Mullholland, who told him she had been murdered by a doctor at the behest of her brother-in-law, James Mullholland, to keep her from returning to Canada, and who had committed another murder and dumped the body in Frains Lake. His claims were investigated but were not substantiated. This spectral visitation would later become known as the "Dixboro Ghost.
