Dana Tyron Rohrabacher (born June 21, 1947, in Coronado, California) is a Californian politician, who has been a Republican member of the United States House of Representatives since 1989, currently representing California's 46th congressional district.

Rohrabacher graduated from Palos Verdes High School in Palos Verdes Estates, California, attended Harbor Junior College, and received his bachelor's degree in history from California State University, Long Beach in 1969. He received his master's degree in American Studies from the University of Southern California. While in grad school and during the early seventies he had a side activity as a folk singer.

In his younger years, Rohrabacher was an active libertarian associated with Samuel Edward Konkin III, but after undergoing something of a political conversion, Rohrabacher became a conservative Republican and served as assistant press secretary to the 1976 and 1980 presidential campaigns of Ronald Reagan. From 1981 to 1988 he was one of then President Reagan's senior speechwriters. During his tenure at the White House, Rohrabacher played a leading role in the formulation of the Reagan Doctrine. He also helped formulate President Reagan's Economic Bill of Rights, which were a series of policy proposals President Reagan introduced in a speech at the Jefferson Memorial.
