Hero is the debut Japanese studio album (seventh overall) of South Korean boy band Super Junior, released on July 24, 2013 under Avex Trax in Japan. The album placed first in the Oricon Daily Chart on its first day of sales.

After releasing a series of singles ("Bonamana", "Mr. Simple", "Opera", "Sexy, Free & Single"), the group released their first Japanese album in July 24, 2013, coinciding their Super Show 5 in Tokyo that same week. Although the singles were not considered by their management label SM Entertainment as their official Japanese promotional efforts, all the singles sold favorably. Most were within top two of the Oricon Weekly Singles Chart and three were certified Gold by the RIAJ for selling over a hundred thousand copies in Japan. Most of their Japanese releases came out to conicide with their concert in the country that week.

The album's first disc comprises thirteen tracks (with one being a bonus track). The second disc contains Japanese versions of the group's subgroup singles and its b-sides, and the DVD contains music videos, behind-the-scenes of music video making, and live performances from their recent concert in Japan, specifically from a-nation and subgroup Super Junior K.R.Y. Special Winter Concert.

Super Junior had release events in Tokyo and Osaka during August and promoted 'Hero' during Super Show 5 at Tokyo Dome, Tokyo, July 27 and 28, and through A-Nation. Super Junior had a meeting with E.L.F Japan official fan club members at Saitama Super Arena in September to promote the album.
