"Saint or Sinner" is the second official single by British rapper Aggro Santos released on 22 August 2010.

It reached number 19 on the UK Singles Chart.

Fraser McAlpine of BBC Chart Blog wrote dismissively of the song, saying that Santos was turning into "Pitbull Junior" with the song's shallow focus on girls.

Santos had a competition on his website with appearance in the video as a prize.
