The Chesapeake Employers Insurance Arena is a basketball arena, concert and multi-purpose event venue on the campus of the University of Maryland, Baltimore County (UMBC) in Catonsville, Maryland. It is the home of the UMBC Retrievers men's and women's basketball teams as well as the volleyball team and serves as a replacement to the Retriever Activities Center (RAC). It has a capacity of 5,000 seats, approximately 1,000 more than the RAC, and is the campus venue for all commencements and concerts. Construction began in March 2016, with an estimated cost of $67 million. Although the venue was originally supposed to be completed in time for the beginning of the Fall 2017 semester and the start of the 2017–18 athletic season, due to delays it officially opened for the February 3 men's basketball game against Vermont.
