         5 . The refrigerator of  claim 3 , wherein the coupling hole includes a plurality of coupling holes, and the plurality of coupling holes are defined to be spaced apart from each other along the height direction of the door. 
     
     
         6 . The refrigerator of  claim 5 , wherein a separation distance between the plurality of coupling holes adjacent to each other is smaller than a height of the accessory body. 
     
     
         7 . The refrigerator of  claim 5 , wherein the plurality of coupling holes adjacent to each other are spaced apart from each other by a preset spacing along the height direction of the door. 
     
     
         8 . The refrigerator of  claim 7 , wherein the coupling protrusion includes a plurality of coupling protrusions, and the plurality of coupling protrusions are disposed to be spaced apart from each other along the height direction of the door,
 wherein a separation distance in the height direction of the door between the plurality of coupling protrusions adjacent to each other is an integer multiple of the preset spacing.   
     
     
         9 . The refrigerator of  claim 7 , wherein the coupling protrusion includes:
 a first body protruding from the accessory body toward the guide;   a second body extending downward from the first body; and   a hooking groove defined between the accessory body, the first body, and the second body.   
     
     
         10 . The refrigerator of  claim 9 , wherein the coupling protrusion includes a plurality of coupling protrusions,
 wherein a separation distance in the height direction between a first body included in a coupling protrusion located closest to an upper end of the accessory body among the plurality of coupling protrusions and the upper end of the accessory body is smaller than twice the preset spacing.   
     
     
         11 . The refrigerator of  claim 1 , wherein the guide includes a first guide located at one side in a width direction of the door and a second guide located at the other side in the width direction of the door. 
     
     
         12 . The refrigerator of  claim 1 , wherein the guide is connected to an external power supply,
 wherein the accessory coupling portion includes an electrode and receives power from the guide when being coupled to the guide fastener.   
     
     
         13 . The refrigerator of  claim 12 , wherein the guide includes a first guide located at one side in a width direction of the door and a second guide located at the other side in the width direction of the door,
 wherein the accessory coupling portion includes a first accessory coupling portion coupled to a guide fastener disposed in the first guide and a second accessory coupling portion coupled to a guide fastener disposed in the second guide,   wherein the first guide and the second guide are connected to power supplies of different polarities.   
     
     
         14 . The refrigerator of  claim 1 , wherein the accessory body includes a support plate forming a bottom surface and supporting an object upward and an extending plate disposed along a perimeter of the support plate and extending upward from the perimeter of the support plate,
 wherein the accessory coupling portion is formed on one surface of the extending plate facing the guide.   
     
     
         15 . The refrigerator of  claim 1 , wherein the accessory is formed as a dispenser accommodating a storage item therein or discharging the storage item therefrom. 
     
     
         16 . The refrigerator of  claim 1 , wherein the door includes:
