After Grêmio turned down his extension request at the end of the season, Dida signed a two-year deal with archrival Internacional on 26 December 2013. He downplayed the rivalry between the clubs, citing that he had wanted to remain in Porto Alegre for family reasons. Due to injury, Dida did not make his debut until 23 February 2014 in a 1–0 loss to Veranópolis, but was able to supplant brothers Alisson and Muriel for the starting spot, making 27 total first-team appearances as Internacional would finish third in Série A and win the 2014 Campeonato Gaúcho.
