Luis Eduardo Barros Cavalcanti (born 9 July 1981), known as Dado Cavalcanti, is a Brazilian professional football coach and former player who played as a left back.

Born in Arcoverde and raised in Caruaru, Cavalcanti joined Santa Cruz's youth setup in 1997, aged 17. Released in 2000, he moved to Naútico, but failed to impress.

Cavalcanti began his career after an invitation from Muricy Ramalho, at that time Náutico first-team trainer, and subsequently joined the youth team's staff. In 2006, after a year as Sport's assistant, he was appointed head coach of Ulbra Ji-Paraná, and went on to win two consecutive Campeonato Rondoniense titles with the club.

Cavalcanti subsequently took over Brazsat FC during the 2008 season, winning the year's Campeonato Brasiliense Terceira Divisão. He subsequently joined Santa Cruz; initially an assistant to Lori Sandri, he became first-team coach after the latter's dismissal in early 2010.

Cavalcanti left Santa in July 2010, and was named América-RN head coach on 13 September. Despite failing to avoid relegation, he remained in charge of the club until the following March, when he was dismissed.

Cavalcanti subsequently managed Central, Icasa, Ypiranga-PE and Luverdense in the following two years, winning the Campeonato Mato-Grossense with the latter. Ahead of the 2013 season, he was appointed Mogi Mirim head coach, taking the club to the semifinals of the year's Campeonato Paulista and being named the best head coach of the tournament.

On 6 May 2013, Cavalcanti was named head coach of Paraná. On 13 December, he was appointed head coach of state rivals Coritiba for the 2014 campaign, but was sacked the following 31 March after being knocked out of the Campeonato Paranaense.

On 13 April 2014, Cavalcanti took over Ponte Preta in the place of departing Vadão, but was relieved from his duties on 21 July. On 12 August, he was named in charge of first club Náutico, leading the club to a 13th position in the Série B.
