Gabriel Truman (born c. 1975) was a wizard and a Hufflepuff student at Hogwarts School in his youth. In the early 1990s, he was one of the school's prefects, and dutifully welcomed Hufflepuff first years to Hufflepuff Basement with a short speech. 
- "I got into big trouble during my third year for duelling a Ravenclaw prefect who insisted that Bridget Wenlock had come from his house, not mine. I should have got a week of detentions, but Professor Sprout let me off with a warning and a box of coconut ice."

In his third year, he landed in trouble by getting into a duel with a Ravenclaw prefect who argued that the famous Arithmancer Bridget Wenlock must have been in his own house, not Hufflepuff, as she was in fact. Gabriel felt he deserved a week's worth of detentions for his own actions, but Professor Sprout went easy on him, sending him off with a warning and a box of coconut ice.
By the 1991-1992 school year, Gabriel had been made a prefect himself and, after the Start-of-Term Feast on 1 September, 1991, welcomed the Hufflepuff first years as they arrived at Hufflepuff Basement with a short speech about the House traditions, symbols, characteristics, and famous past students.
