In June 2015, Volland captained the under-21 team at the 2015 European Championship in the Czech Republic, starting all four matches. In their opening game at the Letná Stadium in Prague, he assisted on Emre Can's 17th-minute equaliser from the edge of the penalty area in a 1–1 draw against Serbia. In their second group match at the Eden Arena in Prague against Denmark, he opened the scoring in the 32nd minute with a smart finish, following Emre Can's slide-rule pass. Volland doubled the lead three minutes into the second half thanks to a delightfully weighted free-kick from 25 metres out. Matthias Ginter rounded off the scoring to head in Amin Younes' cross just five minutes later leading to a 3–0 victory. Volland was awarded the Silver Boot as second highest goalscorer with two goals and one assist, and was also included in the team of the tournament.
