The Grenke Freestyle Chess Open was an open Chess960 tournament. It took place from 17 April to 21 April 2025 in Karlsruhe, Germany. It was held concurrently with the Grenke Chess Open as part of the annual Grenke Chess Festival, supplanting the former round-robin Grenke Chess Classic. It was a part of the Freestyle Chess Grand Slam Tour, a series of Chess960 tournaments being held throughout 2025.

Magnus Carlsen won the tournament with a perfect score, winning all nine of his games. Seven players tied for second place, with Parham Maghsoodloo finishing second with the best tiebreak score. The winner was set to qualify to the Las Vegas Freestyle Chess Grand Slam. Since Carlsen had already qualified from a previous event, the spot was awarded to Maghsoodloo.
