The Binghamton University Explorchestra (commonly known as "Explorchestra" or "Explo"), is a composers' orchestra based in Binghamton University in Binghamton, New York. The ensemble performs exclusively original music.^[1]

Founded in 2009 by sophomores James Mayr, Maxim Pekarsky, and Manar Alherech, Explorchestra has premiered hundreds of new works by university and guest composers. The ensemble is dedicated to promoting new music in all genres by composers from diverse backgrounds. Explorchestra consistently performs original contemporary classical repertoire, jazz, symphonic rock, folk music, concert band, film music, and videogame music.

All members of Explorchestra have the opportunity to submit and, if they choose to, conduct new works. Explorchestra members learn the many facets of leading a modern orchestra, from conducting, arrangement, and audio production to arts management, fundraising, and marketing.

An increasingly important member of the Broome County arts community, Explorchestra partnered with the Binghamton Philharmonic Orchestra to offer its first Composers' Competition in 2011 and again in 2022. The orchestra also collaborates with local businesses and campus organizations, supporting arts, sports, and fashion shows,^[2] and such charity fundraisers as St. Baldrick's Foundation, Amnesty International, 2011 Binghamton Area floods, and Jump Nation.^[3]

Explorchestra is run by 8 elected executive board members.^[4]
