Joël Ivo Veltman (born 15 January 1992) is a Dutch professional footballer who plays as a centre back for AFC Ajax and for the Netherlands national team. He has made over 150 appearances for the club since his senior debut in 2012.
Veltman began his football career in the youth teams of VV IJmuiden in his hometown of Velsen before moving to Ajax in 2001, where he went through the youth ranks of the club. While playing for the Ajax A1 youth squad in 2011–12, Veltman helped his side to win the Nike Eredivisie league title, as well finishing as runners-up to Inter Milan in the NextGen Series (the UEFA Champions League equivalent for under-20 teams) after losing on penalties (5–3) following a 1–1 deadlock after extra time. He made his official debut for the Ajax first team on 19 August 2012 in an away match against NEC in Nijmegen, entering as a substitute for Mitchell Dijks in the 79th minute; the match ended in a 1–6 win for Ajax. Following a successful starting season with the Ajax first team, helping his side secure its third-straight national title and his personal first, on 6 June 2013 it was announced that Veltman had extended his contract with Ajax for another four years, binding him to the club until the summer of 2017.
