Kurz was appointed in June after club legend Kevin Muscat’s departure at the end of last season but the 50-year-old has paid the price for Victory’s inconsistent form.
They sit sixth on the ladder with just four wins and their haul of 15 points at this stage of the campaign is their equal lowest (level with 2007-08 and 2011-12).
The club confirmed the decision in a brief statement on Wednesday morning.
Kurz’s assistant coach Filip Tapalovic has also been dismissed.
Spanish assistant Carlos Salvachua will take over as coach for the remainder of the season, starting with Friday’s match against Adelaide at Coopers Stadium.
Kurz’s last game in charge was the 3-2 defeat to lowly Central Coast Mariners on Sunday.
He was dismissed for arguing with the fourth official on the touchline after Victory conceded two stoppage-time penalties in the loss in Gosford.
Kurz’s dismissal comes less than a week before the Victory play their Asian Champions League playoff at home against Bali United on Tuesday.
A win in that qualifier would send them to Japan to face Kashima Antlers on January 28.
Kurz’s brief time in charge is not the shortest spell at the helm for a Victory coach.
Northern Irishman Jim Magilton lasted just 12 games in 2012 campaign, winning just two matches while Mehmet Durakovic was in the seat for just 14 matches that same season.
A former Bundesliga player with stints at Borussia Dortmund and Schalke during the 1990s, Kurz managed several clubs in Germany before being named Adelaide’s boss in 2017.
He led the Reds to two successive FFA Cup finals, winning the trophy in 2018, but left them at the end of last season when his contract was not renewed.
