The gym leaders in Kanto don't have any specific order so there is no "third" gym. It will make things alot easier for people to answer this kind of question if you specify which town the gym is in and not the number as there are alot of possibilities when you just say third. For example, you get to viridian defeat that gym and go to saffron (defeat that gym), then celadon, celadon would then be the third gym. You can also do these in a different order. Then there is also the possibility that you were counting them from the red, blue, yellow perspective and meant the gym in either viridian or cerulean. Please make a new question specifying the town this gym is in and I am sure you will get the answer you are looking for
The third Gym Leader Erika, and it is located in Celadon City
