Jon Aurtenetxe Borde (born 3 January 1992) is a Spanish professional footballer who plays mainly as a left-back but also as a central defender for Primera Federación – Group 1 club SD Amorebieta.

Born in Amorebieta-Etxano, Biscay, Aurtenetxe joined Athletic Bilbao's youth system at the age of 10, arriving from neighbouring SD Amorebieta and being a finalist in the Copa del Rey Juvenil in 2009[1]– he would lift the trophy the following year.

[2] On 16 December of that year, even before playing his first game with the reserves, the 17-year-old appeared for the first team in the UEFA Europa League, featuring the full 90 minutes in a 3–0 group stage home loss against SV Werder Bremen.

[4] His season was curtailed by a serious shoulder injury,[5] and he was definitely promoted to the main squad for 2011–12 under new manager Marcelo Bielsa;[6] he played 54 official matches during the campaign and scored four goals to help the Basques to reach both the Copa del Rey and the Europa League finals,[7] netting an important one in the club's 2–1 away defeat to Sporting CP in the latter competition's semi-finals (4–3 aggregate victory).

[12] In August 2017, after some weeks without a club, Aurtenexte joined Segunda División B's Amorebieta, returning to where he had played as a child 15 years earlier and reuniting with his former Athletic teammate Joseba Etxeberria who was now acting as manager.
