Change of water storage over Middle East and North Africa (MENA) domain is presented during the period 2003-2017 using satellite data which is provided by the space mission, Gravity Recovery and Climate Experiment (GRACE). Thirty-five basins over MENA domain are selected. Fourteen basins showed positive trend (increase) in water storage while the remaining basins showed negative trend (decrease) in the water storage. Our analysis revealed that most of the basins near the equator had positive trend (increase in storage) in groundwater changes in addition to showing periodic (increasing and decreasing) change. Volta basin highest monitored groundwater storage with 24.5cm within year 2010. On other hand, basin CHAASBasin174 has the lowest negative water storage by 20.5cm during year 2015.
