The Stony Brook University Research and Development Park is a research and development park located in Stony Brook, New York owned by Stony Brook University, which acquired the land through eminent domain in 2005. The park is located a mile from the center of campus along Stony Brook Road on an area spanning over 240 acres in size.
The land was originally owned by St. James Gyrodyne Company of America and acquired by the university in a controversial eminent domain case in which the courts decided against the state's $26 million appraisal in support of the owner's $126 million valuation and later denied the state's request for appeal. The state ended up paying $167.5 million in a lawsuit settlement in 2012
