SS Galileo Galilei was an ocean liner built in 1963 by Cantieri Riuniti dell' Adriatico, Monfalcone, Italy for Lloyd Triestino's Italy–Australia service.

On 23 March 1963, the ship entered service for Lloyd Triestino, doing Mediterranean cruises before departing on its official maiden voyage from Genoa, Italy to Sydney, Australia on 22 April 1963.

[4] The ships were very successful until the 1973 oil crisis, which, combined with the increasing prevalence of airliners, contributed to the decline of ocean liners.

[4] Galileo Galilei returned to Genoa and repaired after she struck a reef off the coast of West Africa on 13 January 1975.

On 20 May 1999, the vessel suffered an engine room fire, which cut all power and caused her to sink in the Strait of Malacca on 21 May 1999 at 0121 hrs.
