Temari. In the beginning of the series people thought that Shikamaru and Ino would be together but he never liked her. Temari liked him after their battle in the Chunin Exam's and even more after she saved him from Tayuya, his dad said he would fall for a troublesome girl so he gave into his feeling and in Shippuuden he and Temari date.

Actually, Kishimoto, who is the guy writing and drawing Naruto, has said in an interview that he doesn't have any plans to write Shikamaru anything romantic. It's still unclear whether or not this means Shikamaru will wind up with anyone.
Actually almost everyone end up with some one be in the ending of the manga. He ends up with temari and has a child with her.
