In 1967 the Student Council sponsored a contest to name a school mascot. Students submitted a variety of ideas from which the faculty chose five finalists. The student body then voted on the nominations, and the Griffin secured the majority of the ballots. This mythical creature, half bird - half animal, is usually represented as having the head, beak, and wings of an eagle with the body and legs of a lion. The Griffin symbolizes vigilance, swiftness, loyalty, and strength. It chiefly functions as protector of man, and the earth's treasures, as well as a guardian of the dead. In the Christian tradition, the Griffin suggests Christ's two-fold nature. The eagle portion represents His divinity, and the lion portion denotes His humanity.

In 2025, nearly six decades after the Griffin was first chosen as our school’s symbol, our faculty, students, staff, alumni, and community members united in a spirited effort to “SAVE THE GRIFFIN.” This heartfelt campaign raised the funds needed to purchase a brand-new mascot costume and continue the proud legacy of our beloved Griffin. Representing vigilance, loyalty, and strength, our reimagined Griffin made his official debut during the 2025–2026 school year and has since become a spirited presence at Donovan Catholic, energizing crowds, rallying school pride, and proudly representing our rich tradition.
