Menz or Manz (Amharic: መንዝ, romanized: Mänz) is a former subdivision of Ethiopia, located inside the boundaries of the modern Semien Shewa Zone of the Amhara Region. William Cornwallis Harris described Menz as lying "westward" of Gedem but between that former province and Marra Biete.
Donald Levine explains that Menz was divided into three parts: Mama Meder in the center; Lalo Meder in the south; and Gera Meder in the north. Further, he defines its boundaries as "the Mofar River in the south, the Adabay and Wanchet rivers in the west, the Qechene River in the north, and in the east a long chain of mountains which pour forth the waters that drain across Manz and which divide it from the lowlands of Efrata, Gedem, and Qawat." This would roughly equate to the modern woredas of Gera Midirna Keya Gebriel and Mam Midrina Lalo Midir.
