Comstock Hall is a building of Cornell University, located in Ithaca, in the U.S. state of New York.
The "old" Comstock Hall was built by New York State for the Entomology Department, but in the 1980s, it was sold to Cornell so that mainframe computers could be relocated from Langmuir Laboratory.
The building was named in honor of John Henry Comstock.
The first floor also hosts some of the faculty and administrative staff for Cornell's Department of Statistics and Data Science.
A reference to Comstock Hall was made in TV show The Office between Andy Bernard and Dwight Schrute[citation needed].
