Orochimaru is not present at Naruto's wedding to Hinata.
While Orochimaru is a prominent character in the Naruto series, he is not invited to Naruto's wedding. This is due to his past actions and his continued pursuit of forbidden knowledge, which makes him a dangerous and untrustworthy individual.
The wedding is a celebration of Naruto's growth and his commitment to his family and friends. Orochimaru's presence would be unwelcome and disruptive to the festivities.
Furthermore, Orochimaru is not a character who values traditional social norms or conventions. He is more interested in pursuing his own goals, regardless of the consequences. It is unlikely that he would even be interested in attending a wedding, even if he were invited.
Therefore, it is safe to say that Orochimaru is not present at Naruto's wedding.
