Luis Enrique was chosen ahead of Chile's Jorge Sampaoli and Bayern Munich's Pep Guardiola for the prize, which is based on votes from international captains, coaches, and selected members of the global media.
In his first season in command, the former Celta Vigo coach guided the Camp Nou side to a historic triple of La Liga, Copa del Rey, and Champions League.
Luis Enrique, who was not present at the ceremony, also won the FIFA Club World Cup in 2015, with Barcelona overcoming River Plate in the final last month.
Luis Enrique is the sixth different coach to win the award, and the second Barcelona coach to do so after Pep Guardiola in 2011.
Bundesliga champion Guardiola entered the top three for the fourth time in six years, while Chilean coach Jorge Sampaoli reached the Copa America final for the first time in his career.
'It must have been a very tough choice because the other contenders were very, very high quality,' said Barca technical secretary Robert Fernandez, who accepted the prize on Luis Enrique's behalf.
'Luis would want to share this award with the staff, the president, the board, the fans, and our players, as there have been many people who have supported him in both good and bad times. This is a fantastic dream team that has helped us advance.'
