The '''Military Grid Reference System''' ('''MGRS''')<ref name="DMA8358_1_Chapter3">[http://earth-info.nga.mil/GandG/publications/tm8358.1/tr83581b.html#ZZ26 DMA Technical Manual 8358.1, Chapter 3.] Datums, Ellipsoids, Grids, and Grid Reference Systems</ref> is the geocoordinate standard used by [[NATO]] militaries for locating areas on Earth. The MGRS is derived from the [[Universal Transverse Mercator coordinate system|Universal Transverse Mercator (UTM)]] grid system and the [[Universal polar stereographic coordinate system|Universal Polar Stereographic (UPS)]] grid system, but uses a different labeling convention. The MGRS is used as [[geocode]] for the entire Earth.
 
An example of an ''MGRS coordinate'', or ''grid reference'', is [{{Coor URL}}21_18_3421_24_35.0_N_157_55_043062452380_N_157_54_57.7_W_89102787040_W_&language=en <code>4Q FJ 1234 6789</code>], which consists of three parts:
* <code>4Q</code> (grid zone designator, GZD)
