Capcom Cup 2015 was an professional Ultra Street Fighter IV video game tournament that was held at Moscone Center in San Francisco on December 6, 2015. 32 players qualified for the tournament by winning one of the 16 Capcom Pro Tour Premier Events or by acquiring points at them. Kun Xian Ho won three of the Premier Events, coming in third place at the Capcom Cup. Many high-profile players, including Justin Wong and Bonchan, lost two consecutive matches during the early rounds of the Cup and were eliminated. The Grand Final was a match between Mad Catz' Daigo Umehara playing as Evil Ryu and Kazunoko playing as Yun, the latter winning the match 3-2.

Being sponsored by Sony Interactive Entertainment for the first time, Capcom Cup 2015 and its Pro Tour had a total prize pool of $500,000 USD, $120,000 of which was awarded to Kazunoko. Capcom Pro Tour 2015 saw a rule change where an automatic qualification would be eliminated and converted into points if the top four winners of a Premier Event had already qualified for the Cup.

The event was the last major tournament before Ultra Street Fighter IV would be succeeded by Street Fighter V, which was created with professional competition in mind.

A series of qualifying events for the tournament were held throughout the year, known as the 2015 Capcom Pro Tour. The Pro Tour consisted of 16 "Premier Events", divided into four "regions", them being North America, Europe, Asia, and "Wild Card". The 16 Premier Events of the 2015 Capcom Cup were as followed:

$500,000 USD was made available as prize money for the entire Capcom Cup, donated by Capcom, Twitch.tv, and new partner Sony. Each of the Premier Events had a prize pool of $15,000 USD to be split among the Top 8 winners. The 2015 Evolution Championships, one of the "Wild Card" tournaments, had a prize pool of $50,000 USD, $20,000 of which was awarded to the tournament's champion. Capcom stated in their press release that they had three goals in mind for the 2015 season, the first being to "give fans more Street Fighter content to enjoy and look forward to," the second being to distribute tournaments and points more evenly across the different world regions, and the last being to increase tournament prize pools in order to incentivize more players to participate.
