Marcos Marcello Trad (born August 28, 1964) is a Brazilian lawyer and politician who served as the 64th Mayor of Campo Grande from 2017 until his resignation from office in 2022.

Prior to this, he was a city councilor for Campo Grande from 2005 to 2007 and a state deputy for Mato Grosso do Sul from 2007 to 2016, serving three consecutive terms.

As a lawyer, he was a member of the Mato Grosso do Sul section of the Brazilian Bar Association, serving as a counselor and later presiding over the Ethics and Discipline Commission.

[10] In December 2010, Trad stirred controversy by stating during a legislative session that it was "impossible to live on R$ 11,000," referring to his monthly salary which had recently been increased to R$12,300.

[12] In September 2016, "Veja" magazine published excerpts from phone taps related to Operation Coffee Break, which investigated a scheme to impeach Mayor Alcides Bernal.

In the recordings, councilor Flávio César (PSDB) asked former mayor Nelson Trad Filho to involve Marquinhos in garnering votes for the impeachment.

[14] Later in September 2016, a social institution employee accused Trad of deception, claiming she was misled into attending a work meeting that was actually a campaign event.
