Based on the water footprint theory of crop production, we analyzed the water footprint of main crop production in 13 Jing-Jin-Ji regions(2 municipalities and 11 prefecture-level cities)in 2014. Meteorological and agricultural basic data was analyzed by combing the Penman equation with CROPWAT software. The results showed that: the water requirement of wheat in the whole growth period was mainly blue water footprint, but green water for maize in this area; The total water footprint for five crops production in the Jing-Jin-Ji Region in 2014 was 437. 03 billion m³, of which green water footprint was 137. 71 billion m³, blue water footprint was 176. 03 billion m³ and grey water footprint was 123. 30 billion m³; In terms of the spatial distribution of the total water footprint of these five crops in the Jing-Jin-Ji Region, we found that the main crop production of Cangzhou, Baoding, Handan, and Shijiazhuang major contribution to water footprint.
