Sir James Alexander Kilfedder (died 1995) was a Northern Ireland unionist politician. He was Member of Parliament for West Belfast from 1964 until 1966 and for North Down from 1970 until his death in 1995. Initially a member of the Ulster Unionist Party, he left it in the late 1970s in opposition to the party's new policy of integration, preferring to advocate the restoration of the Stormont Administration. For a time he sat as an Independent Ulster Unionist, then in 1980 he formed the Ulster Popular Unionist Party from 1980. The party did not outlive him.
Sir James died in 1995 shortly after receiving a letter from OutRage! threatening to expose him as a homosexual.
