Answer:
"Naruto's Wedding" (ナルトの結婚, Naruto no Kekkon) is episode 494 of the Naruto: Shippūden anime
Explanation:
The preparation for the wedding was shown in “The Message”, which was episode 501 of Naruto: Shippuden, but the actual wedding was never shown on screen; fragments from the wedding were shown in The Last: Naruto the Movie, but that is all the anime fans got to see.
