The automatic fish hook tying device includes a hollow housing with an elongate slot formed therein. A fish hook holding assembly near one end of the slot adjustably holds a fish hook thereon, with an eye of the fish hook extending into the housing. A fishing line feeding assembly near the opposite end of the slot positively feeds a fishing line through a fishing line guide assembly, threading the line through the eye. A winding and spooling assembly winds the line around a detachable spool and forms coils around a standing line to initiate formation of a knot. A manipulator assembly carries the spool to form loops and thread the line through the loops during the knot tying process. Upon completion of the knot, the tied fishing hook can be removed from the housing through the slot. A cutter assembly is provided to cut off excess length of line.
