There is no official information or confirmation about Gaara having a wife in the Naruto manga or anime series. Therefore, any information about Gaara’s wife would be purely speculative and based on fan theories or interpretations.

Gaara is a fictional character in the Naruto franchise created by Masashi Kishimoto. He is the youngest of the three siblings from the Sand Village’s ruling family. He has a unique ability to manipulate sand and is known as the “Gaara of the Sand Waterfall” due to the sand waterfall that forms around him.
Throughout the series, Gaara has had many close relationships with other characters, including his siblings, Temari and Kankuro, and his fellow ninja from the Sand Village. However, there has been no indication that he has a romantic interest or is married to any of these characters.
In the spin-off series “Boruto: Naruto Next Generations,” which takes place after the events of Naruto, Gaara is shown to be the Kazekage, the leader of the Sand Village. He is depicted as a wise and respected leader who is dedicated to protecting his village and promoting peace between the ninja nations.
In conclusion, while Gaara is a beloved character in the Naruto franchise, there is no evidence or official confirmation about his marital status. Any information about Gaara’s wife would be pure speculation and should be taken with a grain of salt.
