Marco Jhonfai Fabián de la Mora (Spanish pronunciation: [ˈmaɾko faˈβjan]; born 21 July 1989) is a Mexican professional footballer who plays as an attacking midfielder.

Fabián was recruited by Guadalajara, and spent ten years in the Chivas youth system, including appearances for their affiliate club Tapatío.

[9] On 26 December 2014, after his loan deal expired, Cruz Azul opted not to exercise their purchase option due to Fabián's high expense.

[10] In his return to the Omnilife Stadium, on 18 January, Fabián scored his first goal of the Clausura 2015 tournament against UNAM in a 2–1 home victory.

[13] On 18 December 2015, Guadalajara announced Fabián was sold to German Bundesliga side Eintracht Frankfurt for a transfer fee of US$4 million on a three-year contract.

[16] He made his official debut coming on as a substitute for Haris Seferovic in the 45th minute in a home match against VfL Wolfsburg on 24 January 2016.

[17] On 15 October, Fabián connected with his chest off a Timothy Chandler cross as Frankfurt held Bayern Munich to a 2–2 draw.

[20] On March 2, Fabian made his MLS debut against Toronto FC, scoring his team's lone goal of the encounter, losing 1–3.

[26] On 29 September 2023, Fabián completed his return to Europe, joining Andorran side Santa Coloma on a free transfer, signing a 6-month contract.

[27] In December 2023, Fabián joined the Major Arena Soccer League (MASL) by signing with the Empire Strykers in Southern California on a two-year contract.

[28][29] Fabián's signing was expected to lure other out-of-contract professional players to MASL, beginning with former Mexico teammate Miguel Ángel Ponce.

[29] Fabián was selected by coach Juan Carlos Chávez to participate in the 2009 CONCACAF U-20 Championship held in Trinidad and Tobago.

Fabián showed great skill and workmanship throughout the group stage match and helped Mexico reach the knockoff round.

During the Gold Cup 2011, Fabián was named as one of the replacements for the five players who tested positive for clenbuterol, but would only be called to join them in an emergency, because he was already in concentration with the under-22 squad in preparation for the Copa América.

[30][31] In 2011, Marco was called up by Luis Fernando Tena to form part of the "unofficial national team" composed entirely of players under the age of 22 to compete in the 2011 Copa América.

He started most of the preparation games and scored a few goals before being suspended for six months, along with seven more players, for breaking disciplinary codes at their concentration hotel in Quito.

[33] In May 2018, Fabián was named in Mexico's preliminary 28-man squad for the World Cup,[34] and in June, was ultimately included in the final 23-man roster.

[35] He would only appear in Mexico's final group stage match against Sweden, substituted in at the 67th minute for Jesús Gallardo in a 3–0 loss.
