Ruth's Chris Steak House (NASDAQ: RUTH) is a chain of over 120 steakhouses across the United States and in several international locations. The restaurant is regarded as an upscale fine dining establishment, marking a gradual elevation in its status since its founding in the 1960s. Ruth's Chris is currently the largest luxury steak company, larger than other restaurants such as The Palm and Morton's chains in number of locations, operating income, and overall profit. On March 22, 2008 the company announced it would be seeking stockholder approval to change its name to Ruth's Hospitality Group to better represent the business after the acquisition of Mitchell's Fish Market.

The chain was founded by the late Ruth Fertel, a single mother of two, in 1965, after she bought the existing Chris Steak House in New Orleans. In buying the restaurant, Fertel had to agree that the restaurant keep the "Chris" name for a specified period of time. After the original location sustained a kitchen fire, she relocated the restaurant about one-half mile (0.9 km) to the west on Broad Street and renamed the rebuilt establishment "Ruth's Chris." Under the purchase agreement, the name "Chris Steak House" could not be used at any other location, and she did not want to lose customers already familiar with the Chris name. Fertel started to franchise the restaurant in the 1970s to locations throughout the United States and throughout the world.

Advertising efforts are primarily focused in the talk radio market and its male demographic. The chain has cultivated paid endorsements from several radio celebrities, including Rush Limbaugh and Sean Hannity, with the latter proclaiming Ruth's to be his favorite restaurant. Ruth's won the 2006–2007 Golden Icon Award for "Best Steak House Chain"; the Golden Icon Awards are presented annually by Travolta Family Entertainment.
