An integrated fishing rod holder kit incorporates a grip coupler that replaces a butt cap on a preexisting fishing rod that has a hollow rod blank having a void space that extends linearly through from the butt of the rod through a rear grip end and forward through the grip area and reel seat area of the rod towards the fishing rod tip. The grip coupler is securely fixed to the rear grip end coaxially and preferably about the rod blank butt end that is revealed after the butt cap is removed. The grip coupler has external threads on its outer surface for engaging a coupler engagement collar of a rod holder body.A rod holder body has an internally threaded collar coaxial to an elongate support rod shaft having one end mounted within the rod holder body and the free end of the shaft extending through and outward from the threaded collar, the rod holder body has a generally V-shaped holder end at the end opposite the collar, and the support rod shaft is elongate and sized to be removably received within the hollow rod blank of the fishing rod and selectively secured therein by engagement by the collar of the external threads of the grip coupler.When removed from the hollow rod blank of a fishing rod, the rod holder body and attached elongate support rod shaft can be used as a rod holder to prop up the rest of the fishing rod.
