Tens of thousands of Wales supporters travelled to France in the summer to see their side progress to the tournament's semi finals.
They were branded "the red wall" by the Wales players.
Uefa's executive committee has also recognised supporters from Iceland, Republic of Ireland and Northern Ireland.
The announcement coincides with Wales rising to 10th in the Fifa world rankings.

The 52-year-old is returning to Formula 1 from his position as technical boss of Audi's World Endurance Championship programme, which ends this season.
Swiss Zander previously worked for Sauber between 2006 and 2007, and has held senior design positions in a number of other F1 teams.
His most recent F1 role was as deputy technical director of the title-winning Brawn team in 2009.
He also previously worked for Honda, Williams and BAR.
Sauber have faced financial problems in recent years and are currently last of the 11 teams in this year's world championship.
But the Swiss team have hopes of moving up the grid next season following their takeover earlier this year by a Swiss finance group called Longbow.
Zander said: "One of my tasks will be to define a stable and efficient technical organisation that evolves the potential of creativity and, therefore, the basis for the development of successful Formula 1 cars.
"Initially we obviously want to improve and establish ourselves as a team in the mid-field. It is a challenge which I await with excitement and enthusiasm."
Team principal Monisha Kaltenborn said: "This is a very important step in order to guide the team into a new and successful era.
"Zander fits well into our team. He has a lot of know-how in Formula 1, as well as in motorsport in general.
"In our factory in Hinwil, he will have the possibilities to work technically at a very high level. We are convinced we will make progress with him."
Zander joined Audi in 2010 and led the team to five consecutive wins in the Le Mans 24 Hours from 2010-14.

Mike Petter quit his post ahead of the publication, due on Friday, of a Care Quality Commission (CQC) report on Southern Health NHS Foundation Trust.
He said leaving his post had been a "very difficult decision".
Problems came to light at the trust when 18-year-old Connor Sparrowhawk drowned in a bath at a care facility.
An inquest found neglect contributed his death, at Slade House in Oxford, in 2013.
A report commissioned by NHS England, published in December 2015, discovered that only 272 of the 722 deaths in the trust over the previous four years were investigated.
The trust was issued a warning notice by the CQC following an inspection in January.
In a statement Mr Petter said: "The trust has recently undergone a significant amount of scrutiny in some service areas and, given the challenges it faces, I feel it is appropriate for me to allow new board leadership to take forward the improvements.
"I have been involved in Southern Health since the trust was formed in 2011 as a non-executive director and since August 2015 as chairman.
"It is with great sadness that I now leave the organisation.
"I offer my support and best wishes to all our staff whose dedication and commitment I am continuously impressed by."
Wales football fans have been given an "outstanding contribution" award from Uefa for their part at Euro 2016.
