SS Imperator was an ocean liner built for the Hamburg Amerikanische Packetfahrt Actien Gesellschaft (HAPAG) (Hamburg America Line) launched in 1912. She surpassed the RMS Titanic by 24 ft., and she herself was surpassed the same year by SS Vaterland (later SS Leviathan) by 44 ft. She was the first of a trio of successively larger Hamburg America ships that included SS Vaterland and SS Bismarck built by the line for transatlantic passenger service. At the time of her completion in June 1913, she was the largest passenger ship in the world, superseding the RMS Olympic.

During World War I, the ship remained in port in Hamburg. After the war, she was briefly commissioned into the United States Navy as USS Imperator (ID-4080) and employed as a transport, returning American troops from Europe. Following her U.S. Navy service, Imperator was handed over to Britain's Cunard Line as part of war reparations, and she sailed as the flagship RMS Berengaria for the final decade of her career.

The ship was named after the English queen Berengaria of Navarre. Many Cunard ships had been named for parts of the Roman Empire and had names that ended in "ia". RMS Berengaria, like many, but not all, Cunard ships, kept the "ia" ending to her name but, like several Cunard ships before and after, was not named after a province of the ancient world.

Sir Arthur Rostron of the RMS Titanic passenger rescue fame and former captain of Carpathia took command of Berengaria on July 1920. The following year both Berengaria and Aquitania were sent to Armstrong Whitworth shipyards to be converted from coal firing to oil.

In September 1925, a security alert at sea was triggered when the Cunard company offices in New York received a message stating there was a bomb aboard the Berengaria; the vessel was then 1200 miles out from New York, bound for Southampton. The ship was searched, and the passengers and most of the crew were not informed as to the reason. A fire–drill was held just before the supposed time of detonation, so passengers could be placed close by their lifeboat stations without arousing suspicion. The bomb–threat was a hoax. Berengaria was again in the headlines in May 1934, when she ran aground on the mud banks at Calshot on the Solent. She was pulled free from the mud by four Southampton tugs. The vessel suffered no damage and the incident did not affect her sailing schedule.

Despite her German heritage, Berengaria served as flagship of the Cunard fleet until she was replaced by her sister ship, Majestic – ex-Bismarck, in 1934 after the merger of Cunard with White Star Line. In later years, Berengaria was used for discounted prohibition-dodging cruises, which earned her the unfortunate nickname "Bargain-area".

Towards the end of her service life, she suffered several electrical fires caused by aging wiring, and Cunard-White Star opted to retire her in 1938. She was sold to Sir John Jarvis, who also purchased Olympic, to provide work for his local region. She sailed for the River Tyne under the command of Captain George Gibbons and was scrapped down to the waterline. Final demolition took place in 1946.
