Sinan is an impact crater on the planet Mercury, 147 kilometers in diameter. It is located at 15.5°N, 29.8°W, northeast of the crater Yeats and southeast of the crater Li Po. It has one craterlet on the south-southwestern side of the crater floor, and it has a symmetrical pit slightly west of the center. Together with a smaller unnamed crater on its southern border, the crater Sinan forms a shape similar to that of the spade found in card games. The crater is named after Mimar Sinan, a 16th-century Turkish architect. The name was adopted by the International Astronomical Union in 1976.
Sinan is a word found in Aramaic and Early Arabic, meaning spearhead or perhaps spear. It is also possible that the name is derived from the Ancient Greek name Sinon. It was subsequently used as a male given name.

Towns in Guzamn include Rob Gebeya. Sinan was part of Guzamn woreda.
The highest point in this woreda as well as in the Misraq Gojjam Zone is Mount Choqa (also known as Mount Birhan), a part of the Choqa Mountains, with an elevation of 4154 meters above sea level.
