Lorelai and Luke officially get together as a couple in season 5, episode 3 , titled “Written in the Stars.”

That’s the episode where they go on their first proper date and Luke shows Lorelai the horoscope he saved from the day they met, and from that point on they’re considered to be officially dating.

If you’re counting from their first kiss , that happens a little earlier in season 4, episode 22, “Raincoats and Recipes,” which kicks off the romantic shift that leads into their relationship in season 5.

So, in short: first kiss in the season 4 finale, and fully “together” as a couple in season 5, episode 3.
