In the early days, Maryland teams proudly bore the nickname "Old Liners," a nod to the state's historical moniker. Their athletic emblems embodied this identity, often featuring a simple shield emblazoned with a crossed axe and plow – symbols of the state's agrarian roots.

Yet, by the 1930s, the "Old Liners" felt outdated. Enter the Terrapins, a nickname coined by then-football coach Harry C. "Curley" Byrd, inspired by the abundance of diamondback terrapins in the Chesapeake Bay. This sparked a visual transformation, with the first Terrapin mascot appearing in 1932 – a cartoonish turtle sporting a Maryland flag shell.

The 1960s and 70s saw a parade of Terrapin logos, some playful, others fierce. One featured a cartoon turtle balancing a basketball on its nose, while another sported a more aggressive profile, jaws open and ready to bite. These designs, while nostalgic, lacked the consistent identity a growing athletic program needed.

In 1988, the iconic "Maryland M" with the smiling Terrapin emerged. This design, with its bold stripes and playful yet determined mascot, struck a perfect balance between tradition and modernity. It became a ubiquitous symbol, adorning helmets, jerseys, and even buildings, cementing its place as the face of Maryland athletics.

Over the years, the logo has undergone subtle refinements, keeping it fresh while preserving its core identity. The 2012 iteration boasts a sleeker, more athletic Terrapin, reflecting the evolving nature of college sports.
