Mecha is one of the woredas in the Amhara Region of Ethiopia. The name, Mecha, is taken from the name for a subdivision of the province of Gojjam. Part of the Mirab Gojjam Zone, Mecha is bordered on the south by Sekela, on the southwest by the Agew Awi Zone, on the west by the Lesser Abay River which separates it from Debub Achefer and Semien Achefer, on the northeast by Bahir Dar Zuria, and on the east by Yilmana Densa. Towns in Mecha include Merawi and Wetet Abay.
Bodies of water in this woreda include Tingiti, which is located in a volcanic crater near the Lesser Abay; R.E. Cheesman believed he was the first European to see this body of water when he was shown it in November 1932.
