Due to the ever evolving diversity of Miami and the rest of South Florida in general, the name United was chosen as a means of unifying the many different peoples that make up the city, hence one of the club's mottos "Bringing the community together for the LOVE of the game." Unlike other clubs that use the title "United" as an indicator of the amalgamation of two or more clubs to form the one, as in the case of the well known English side Newcastle United, the use of the title "United" serves more as a celebratory and honorary salute to the multiple histories, legacies, players and fans of the four previous clubs that have represented the city over the years, i.e. Miami Gatos, Miami Toros, Miami Fusion, and lastly Miami F.C. While Miami United F.C. has no official affiliation, nor claims to have any affiliation with any of the previous teams, the commitment to honor and celebrate the city's soccer past and cultural diversity remains a great part of the club's identity.
Miami United played and won their first ever game in club history vs Cape Coral Hurricanes, 3–0, May 4, 2013. Miami finished the season coming in 3rd place in the NPSL Sunshine Conference.
2013 brought with it the creation of the youth and women's teams, along with new head coach Ferdinando De Matthaeis. Miami United FC also struck up a partnership with nearby Miami Dade College in a joint effort to develop youth soccer in Miami.
In 2014 Miami United's official jersey and equipment supplier changed. No longer was the team's jersey and equipment supplied by Admiral but instead by the Italian sports apparel company Garman. Italian watch and jewelry maker Gaga Milano also became the team's jersey sponsor. Miami remained heavily engaged in the community forging successful 2nd, youth and women's teams. Miami's 1st team also improved on the field by creating a club that had a mixture of veteran players and younger local players. The club finished the regular season undefeated on top of Sunshine Conference. Miami defeated both Storm FC and Tampa Marauders to claim the 2014 Sunshine Conference title. Miami then went on to face Chattanooga FC in the NPSL Southern Regional Finals, but was defeated. Despite losing to Chattanooga, because Miami won the Sunshine Conference the club still qualified for a slot in the 2015 Lamar Hunt U.S. Open Cup.
