Augusto Sérgio "Guto" Ferreira (born 7 September 1965) is a Brazilian professional football coach.

He won that year's Campeonato Gaúcho and was permanently appointed as head coach on 4 June 2002,[1] but was still sacked on 26 August.

[6] After a spell at 15 de Novembro-RS, he returned to Internacional in 2008, again as an assistant; he was also an interim in June 2008, after the departure of Abel Braga.

[11] Ferreira was dismissed on 6 June 2013,[12] and on 28 July he was named Portuguesa head coach, with the side seriously threatened with relegation.

[13] He managed to finish 12th with the club, but the side ultimately suffered relegation due to irregularly fielding in a player; in the following February, he resigned.

[20] On 11 November 2017, after a 1–1 draw against Vila Nova and thus losing the leadership of 2017 Campeonato Brasileiro Série B, Ferreira was relieved from his duties.

[32] On 9 December, despite avoiding relegation, he was sacked,[33] and was announced in charge of fellow top tier side Goiás the following day.
