Lucas Daniel Wilchez (Spanish pronunciation: [ˈlukas ðaˈnjel wilˈtʃes], born 31 August 1983) is an Argentine former footballer who played as a left winger.

He began his career at the Cambaceres youth squad, then moved to La Plata and joined the football academy of his hometown club, Estudiantes, at eighteen.

In June 2010, it was confirmed that Wilchez signed for Primera División club Colo-Colo, a team led by coach Diego Cagna, who directed him years ago in Tigre.

After his unsuccessful participation with Estudiantes at the 2008 Clausura Tournament, was not retained by Sensini and days later moved to Talleres de Córdoba, signing a one-year contract for the club.

[13] On 19 June 2010, Colo-Colo's magazine Blanco y Negro confirmed that Wilchez joined the club on loan from Estudiantes de La Plata in a one-year deal, reuniting well with Diego Cagna, his coach when he played for Tigre.

[18] Despite winning supporters' affections due to his performances, his charm was marred by Colo-Colo's title loss after Católica's notable comeback in which they surmounted a seven-point difference in the last five weeks.

On 4 July 2012, Terra Chile confirmed that Wilchez will join La Liga side Real Zaragoza for play during the 2012–13 season at the Spanish club in a one–season deal.
