Noite e Dia (Portuguese for Night and Day) is the second and last studio album by Brazilian post-punk band Smack. It was released in 1986 by Baratos Afins.
It is the only Smack release to not feature Edgard Scandurra, since he left the band in the same year in order to give more focus to his alternate band Ira!. He returned to Smack when they reunited in 2005, however. It was also the band's last release to feature Thomas Pappon, since he moved to England in the mid-1990s; he would not partake on the band's reunion.
