tecnically in sunyshore or other city, but then you need to beat the elite 4 in the pokemon league, past that city.

The last gym is in viridian city
gym leader volkner in sunyshore city
the last gym leader is Blue.When you go to the seventh gym leader Blaine you should see Blue and asks you if you have 7 badges then you beat Blaine and go to Blue and he says to meet him at his gym
you must frist go to seafoam island where blaine is, he is the 15th gym leader, then go to cinnibar island and a character who is behind the Pokemon center will then say that he is the last gym leader, once you have talked to him he will go to viridian city gym, he is the last gym leader. this is for heartgold and soulsilver :) hope this helped.
The Kanto gym leaders come in no particular order, but Blaine is typically the last gym leader fought, and also the second to last gym leader appearing on the Trainer Card.
