Macha (Russian: Мача) is a field of five meteorite craters located 685 kilometers (425 miles) northeast of Yakutsk in the Sakha Republic in Siberia, Russia,{{cite Earth Impact DB |name=Macha |accessdate=2009-08-15}} ranging from {{cvt|60|to|300|m|||}} in diameter.{{cite journal |last1=Gurov |first1=E.

The two largest craters form the pear-shaped Abram Lake while the remaining three are located to the north.{{cite web |title=Macha crater field |date=21 January 2013 |publisher=Wondermondo |url=http://www.wondermondo.com/Countries/E/RUS/Sakha/Macha.htm}} They have been very well preserved.

The craters are the result of the fall of possible iron meteorites at approximately 5300 BCE (Holocene), which would give them an age of about 7,300 years.
