Flag for the league itself

This design was based on the league's current logo, with the three stars for club, country, and community.

Atlanta United FC

This design incorporates the phoenix and fire from the seal of the city of Atlanta, combined with the Five Stripes from the crest and original jerseys.

Austin FC

The first of the new additions, Austin gets a design inspired by the city seal as featured on their (admittedly mediocre) city flag, combined with a slight tweak of the tree from the team's crest.

CF Montreal (former Impact)

This one is inspired by the vertical striped jersey, a motif also found in the original crest. As a French-Canadian organization, it absolutely needs the Quebecois Fleur-de-lys.

Charlotte FC

Charlotte gets a design inspired by the Charlotte city flag, simplified and more based around the team's crest. It bares more than a passing resemblance than the flag I designed for the Charlotte Independence in USL.

Chicago Fire

This design gets an update as the Fire have rebranded - twice - since my original design. I kept the bulk of the flag, simply because I was still so pleased with it, but recolored it with the new palette, and incorporated the C and star from the latest crest.

Colorado Rapids

This flag is inspired by the design of the crest, which in turn is inspired by the mountains of Colorado.

Columbus Crew

This one is directly based on the center design of the club's previous roundel-style crest, and isn't getting an update post-rebrand because I hate the new logo and miss the old one.

DC United

This one tends to remind people of Albania's flag, and that's not without merit. This uses the eagle from the second version of their crest.

FC Cincinnati

FC Cincinnati get an update of their USL flag design, which in turn was based on the Cincinnati city flag now incorporated into their new jerseys.

FC Dallas

This one is a modification of the state flag of Texas to incorporate the now-traditional red and white stripe design from the jerseys.

Houston Dynamo

Houston gets a redesign with their new hexagonal rebrand. Taking inspiration from the city flag, this design incorporates the new hexagon and a 6 pointed star for the 6 wards of Houston, along with the lightning bolt for the energy behind the Dynamo brand.

Inter Miami CF

Miami gets a design that incorporates the quirky, angular flamingos of their crest, reduced to a broken saltire design as a compromise between the design used by the cities of Miami and Fort Lauderdale, and those used by Miami-Dade County and the state of Florida. The lines intersect the way Inter is Inter.

Los Angeles FC

This one is a combination of the stylized LA logo from the crest, and the flag of Los Angeles. Normally, I'm quite opposed to lettering on flags, but that winged A is too nice to not use.

LA Galaxy

This flag is inspired by the long-running blue sash jerseys, and the four point star from the crest. This is one of the few designs where I stuck with my first idea.

Minnesota United FC

Minnesota's flag is directly taken from the crest. I love the simplicity of the design, and that fantastic loon.

Nashville SC

Nashville get the design from their prior USL team promoted unchanged, mainly because the old crest was better, but also because the ideas expressed (music, Tennessee, local pride, sound) have easier representation with the older symbolism. Also I still love this design and want to keep it around. Colours updated to reflect their MLS branding.

New England Revolution

This one is based on the unofficial flag of New England, with six stripes for the six states in the region. It also matches the proportions of the club logo.

New York City FC

This flag is based on the flag of New York City, and includes this center design that was based on old subway tokens and subway maps.

New York Red Bulls

This is a massive simplification of the Red Bull logo, turning the winged bulls into bars of solid color.

Orlando City

This flag is heavily inspired by the strong Brazilian influence on both the team and the city of Orlando in general.

Philadelphia Union

This flag is based on the flag of Philadelphia, using the wonderful, simple snake design from the crest.

Portland Timbers

This flag is another design made by simplifying the crest.

Real Salt Lake

This flag features the bicolor design from the flag of Salt Lake City, as well as the crown from the top of the RSL crest.

San Jose Earthquakes

This design is based on the fault line motif from the crest and jerseys.

Seattle Sounders

This one happened partially because of my obsession with Nordic Cross designs, partially because of the Nordic influences in Seattle, and partially because, broadly speaking, Seattle is located in the US's Scandinavia. Also features the simplified Space Needle from the crest.

Sporting Kansas City

This one is another design from a crest. I love the SC design so much, and I think that it's woefully underused, so it's the focal point of this design. The lighter blue stripes are from the right side of the crest.

Toronto FC

Toronto's academy logo is amazing, and that's the design you see here. This one is based on the flag of Canada to make something as distinctly Toronto as possible.

Vancouver Whitecaps

This one is inspired by the representation of mountains on the crest.
