Since 1934, the mascot of UConn has been the husky. (Prior to that year, athletic teams were known as the Aggies.) All UConn huskies are named Jonathan in honor of Jonathan Trumbull, and all but the first, a brown and white husky, have been white. The current "real" Jonathan is Jonathan XII; he is often seen greeting fans and eating dog biscuits at sporting events. Jonathan is one of the few university mascots in the nation to have been selected by students via a popular poll.

Jonathan's name can be found on numerous establishments on campus, including Jonathan's Cafeteria in the Student Union. There is also a statue of Jonathan located outside Gampel Pavilion; it is school tradition to rub the statue's nose for good luck.

The UConn fight song, officially titled UConn Husky, is one of the most recognizable in the country, due in large part to its frequent playing during nationally televised sporting events. The lyrics to UConn Husky are as follows:

An mp3 file of UConn Husky is available on the UConn website[2] .

The colors of UConn are white and national flag blue, though small amounts of red often appear on athletic uniforms. The Pantone standard for the exact shade of blue used is #281.

The visual symbol of the university is the oak tree. This is because the Latin word for oak, robur, also refers to moral and physical strength. The oak leaf appears on the university symbol and next to the word UConn on official letterhead.
