Alpha Chi Alpha

Alpha Chi Alpha (ΑΧΑ, Alpha Chi) is a fraternity at the American Ivy League university of Dartmouth College. Alpha Chi Alpha is a member of Dartmouth's Greek system, which currently has fourteen fraternities, nine sororities and three co-ed undergraduate houses that fall under the umbrella of the Greek system.

Alpha Chi Alpha is referred to among Dartmouth students as simply Alpha Chi. The house which is located at 13 Webster Avenue on the Dartmouth College campus is a college-owned fraternity, meaning that the brothers do not own the land or house. This also means that Dartmouth College paid for $1.3 million in renovations (done during the summer of 2004), which included the razing of the "Barn" structure that was used as social space by the brothers of Alpha Chi to make way for a new expanded basement and main floor area which will act as new social space for the fraternity.

The house is nicknamed the "Magic Green Cottage" and the "Cheese Lodge" by its members and has the unique location on fraternity row directly across from the President's House. The green-shingled structure includes a sand volleyball court adjacent to the house. Its perennial pledges are easily recognized by their "sirens" (red, baseball cap-like headwear), which they wear for the duration of their pledge term.
