Rowe Hessler (born February 27, 1991) is an American speedcuber. He is a two-time former U.S. Champion and was runner-up in the 3ÃÂ3ÃÂ3 event at the 2011 World Championship. He held the world record for both the single and average of the 2ÃÂ2ÃÂ2 event in 2009. Between April and October 2025, he held the world record in 3ÃÂ3ÃÂ3 multi-blindfolded with 63/66 cubes solved, totaling 60 points. Hessler held the North American record for the average of five 3ÃÂ3ÃÂ3 solves from 2009 to 2014, improving the record from 11.11 to 8.27 seconds.
Hessler began competing in official World Cube Association (WCA) events in 2007. At the 2009 World Championship, he won the 2ÃÂ2ÃÂ2 event with an average of 3.28 seconds and secured third place in the 3ÃÂ3ÃÂ3 one-handed event with an average of 20.02. In 2010, he set the North American record for a single 3ÃÂ3ÃÂ3 solve with a time of 6.94 seconds.
In the 2011 World Championship held in Bangkok, Hessler achieved a 9.56-second solve to finish as the runner-up in the 3ÃÂ3ÃÂ3 event. Between 2009 and 2014, he consistently lowered the North American average record for five 3ÃÂ3ÃÂ3 solves, culminating in an 8.27-second average at the 2011 Bridgewater Open.
In December 2015, Hessler attempted to break the Guinness World Record for most RubikâÂÂs Cubes solved in 24 hours at Stony Brook University, drawing support from students and faculty.
Beyond the standard events, Hessler is recognized for his blindfolded solving skills. His 3ÃÂ3ÃÂ3 multi-blind personal record of 63/66 cubes ranked as the world record between April and October 2025, beating Graham Siggins' 62/65, but then beaten by Graham Siggins' 63/65.

In December 2024, Hessler participated in a speedcubing exhibition at a memory-focused event held at a Natick assisted living facility, showcasing the cognitive demands of multi-blind solving.
