The actor played Captain James T Kirk from 1966 to 1969 and in seven subsequent movies, but claimed he had never seen himself in the role.
He also admitted that he had never watched US drama Boston Legal, in which he has played lawyer Denny Crane for the last four years.
The 76-year-old said on his blog: "I never watched Star Trek. I have not even seen any of the Star Trek movies. I don't watch myself. When I direct and have to look at filmed scenes of myself, I suck."
He added that he wished he had held on to some mementos from his time on the cult show, saying: "I've kept nothing. Given the choice at the time of having a Star Trek shirt or a designer suit, I'd have taken a suit. I should have known better."
Shatner has denied reports that he nearly died during a hip replacement operation.
