Tri Repetae (stylised as tri repetae.) is the third studio album by English electronic music duo Autechre, released on 6 November 1995 by Warp in the United Kingdom. The album was released on 16 March 1996 by Wax Trax! Records and TVT Records in the United States as a two-disc set named Tri Repetae++, which included the Garbage and Anvil Vapre EPs constituting the second CD. In Japan, it was released with the bonus track "Medrey".
In contrast to the duo's previous albums, Incunabula (1993) and Amber (1994), Tri Repetae features more minimal, repetitive rhythmic patterns and intricate, spacious melodic arrays. The liner notes of the album mention a preference to listen to the album on vinyl for its inclusion of surface noise. The CD version states that the album is "incomplete without surface noise" whereas the vinyl version states that it is "complete with surface noise".
