Buchanan Ingersoll & Rooney PC is an American law firm and lobbying group based in Pittsburgh, Pennsylvania. The firm has more than 450 lawyers in offices in 15 U.S. cities.[2] As of 2022, Buchanan Ingersoll is the third-largest law firm in Pittsburgh by number of attorneys in its Pittsburgh office.[3]


The firm was founded in 1850 by Congressman Moses Hampton and his son, John. When Moses Hampton became chief judge of Allegheny County, William C. Moreland was brought in as an additional partner in 1868 and the firm was renamed Hampton & Moreland. The firm continued to grow and went through several name changes before incorporating in 1980. The firm shortened its name to Buchanan Ingersoll P.C. in 1983, and acquired two other firms during the 2000s: Burns, Doane, Swecker & Mathis in 2005, and Klett Rooney Lieber & Schorling PC in 2006, leaving the firm with its current name, Buchanan Ingersoll & Rooney.[4]

In December 2016, the firm announced a strategic affiliation with former Florida governor and presidential candidate Jeb Bush in order to boost the firm's practice in Florida, where it has six offices.[5]
