The Railroad Revitalization and Regulatory Reform Act of 1976, Pub.L. 94–210, S. 2718, 90 Stat. 31, enacted February 5, 1976, often called the "4R Act," is a United States federal law that established the basic outlines of regulatory reform in the railroad industry and provided transitional operating funds following the 1970 bankruptcy of Penn Central Transportation Company. The law approved the "Final System Plan" for the newly created Conrail and authorized acquisition of Northeast Corridor tracks and facilities by Amtrak.

The Act was the first in a series of laws which collectively are described as the deregulation of transportation in the United States. It was followed by the Airline Deregulation Act (1978), Staggers Rail Act (1980), and the Motor Carrier Act of 1980.
