The IMP Society is a secret society at the University of Virginia in Charlottesville, Virginia, United States that is notable for combining philanthropy and public mischief.

The Seven Society is the most secretive of the University of Virginia's secret societies. Members are only revealed after their death, when a wreath of black magnolias in the shape of a "7" is placed at the gravesite, the bell tower of the University Chapel chimes at seven-second intervals on the seventh dissonant chord when it is seven past the hour, and a notice is published in the university's Alumni News, and often in the Cavalier Daily. The most visible tradition of the society is the painting of the logo of the society, the number 7 surrounded by the signs for alpha (A), omega (Ω), and infinity (∞), and sometimes several stars, upon many buildings around the grounds of the university.
