SS Stella Solaris (lit. "Star of the Sun", formerly SS Cambodge) was an ocean liner built for Messageries Maritimes in 1953. She mainly provided passenger service between France, the Middle East, Southeast Asia, and Japan.

Stella Solaris was built in Dunkirk in northern France as Cambodge, and along with two sister ships, the SS Viet Nam and SS Laos (all three were nicknamed 'les blancs'/the 'whites' by their crews, because of their colour). She made her first voyage in 1953. After the 1970s, she was bought by a Greek company and converted into a cruise ship. Most of her working life was spent as a cruise ship in the Aegean Sea and she also made frequent transatlantic voyages to South America and the Caribbean Sea. Few major damaging incidents happened to Stella Solaris, and she quickly became one of the more popular cruise vessels of the time. An economic crisis in the cruise ship trade in 2003–2004 caused many older vessels, such as Stella Solaris, to be sold for scrap. After 54 years of service, she was retired in December 2003 and broken up in Alang, Bhavnagar District, India.

The French shipping company Messageries Maritimes ordered three identical ships to be built around the late 1940s to provide passenger and mixed-freight service on a route between Marseilles and Yokohama via ports in South Asia. The first to be completed was Viet Nam in 1952, followed by Cambodge in 1953. Cambodge was built by Société des Ateliers & Chantiers in Dunkirk, Nord, in northern France. The name was derived from Cambodia. Her keel was laid down in 1949 and she was launched on 8 July 1952, then completed and delivered to Messageries Maritimes in July 1953. The third ship, Laos, was not completed until 1954.

Cambodge and her sisters were mid-sized liners. The ship was 13,520 GRT, 545 feet (166 m) long with a beam of 72 feet (22 m). She was powered by twin Parsons geared turbines, which gave her a cruising speed of 21 knots (39 km/h). Cambodge could carry 347 passengers on 7 decks — 117 in first class, 110 in second (tourist) class, and 120 in third (steerage or cabin) class. First class cabins occupied the majority of the passenger space in the central portion of the ship, the second class in the stern, and third class in the bow. First class passengers also had a large pool for their private use. A large amount of artistic flair was employed in the design of Cambodge. A French style predominated, but some Asian decorations were also incorporated. Italian artist Nino Zoncada was hired to design some of the interior of the ship.

F deck was the topmost deck, housing the ship's bridge. Berths for officers occupied most of this deck, but a children's playroom was in the aft starboard corner. The ship's lifeboats were also on this deck. E deck was the middle deck of the ship's superstructure. Most of E Deck consisted of first class cabins. The Drawing Room near the front had a row of windows said to "rival those of Atlantic liners of the time". Aft of the Drawing Room a first-class promenade surrounded nearly the entire interior of the deck. The Bar, Smoking Room and Writing Room were further astern, past the first class cabins. Aft of the public rooms were the outdoor first class swimming pool and lido deck area. The interior of D deck also primarily consisted of first class cabins, many with private balconies. Cabine de Luxe #5, with a separate bedroom and sitting room, was on the forward starboard portion of the deck and was the most luxuriant single berth on the ship. The back portion contained "studio" class cabins that were narrower and smaller than the other first class rooms. The deck also had the forecastle of the ship and the primary navigation equipment. Aft of the fo'c'sle was a third class outdoor area. Aft of the private balconies of the interior first class cabins was a second promenade deck.

C deck was the highest deck within the ship's hull. Third class cabins were in the starboard bow section, and the third class dining room was opposite of the cabins. After the third class area were more first-class cabins, terminating at a stair tower. Aft of the stairwell were second-class berths without private bath facilities, and aft of the second-class rooms was a sheltered promenade. B deck consisted mostly of public space. The first class and tourist class dining areas were both located amidships, separated by the ship's galley. The first class dining saloon was lit with fluorescent lights and equipped with apparatus to minimize sensation of the roll of the ship. The second-class dining area was similar to the first-class area, but not as lavish, and also doubled as the ship's cinema. The bow section of B Deck had more third-class accommodations and the third-class ship entrance. A deck had mostly crew's quarters, storage rooms, and had the ship's engines. There were also third class cabins in the bow. Notably, Cambodge's original steam turbine engine never suffered significant breakdowns and never had to be replaced.

The Sports deck (topmost) was mostly an outside recreation area. Two walkways in the aft section abutted the swimming pools on the deck below. The section closest to the bow lay atop the ship's bridge. Most of the sports deck was a spacious rooftop space. Lido deck constituted the pool area of the ship and also housed the bridge closer to the bow. There were two nearly oval-shaped swimming pools surrounded by a spacious lido area. Ahead of the lido section and behind the officers' quarters aft of the wheelhouse was a small buffet. The interior portion of the deck continued around the lido area via glass-enclosed walkways. These walkways were just inboard of the ship's lifeboats. Boat deck contained most of the first class cabins and there were 34 that were especially luxurious. The Card Room and Reading Room were aft of the passenger accommodations. A teak promenade encircled the entirety of Boat Deck, designed to slope towards its amidships section as a way to compensate for the swaying of the vessel.

Solaris deck consisted almost entirely of public spaces. The main dining room was located just aft of the ship's galley. The much smaller Bar Grill extended aft off the starboard side of the dining area. Amidships, the purser's office and ship's reception area were located in the primary entrance area of Stella Solaris. The Solaris Lounge and Piano Bar were located aft of the entrance hall, both used for various forms of entertainment. Golden deck was the lowest deck on the superstructure and was used for passenger accommodations. The ship's Beauty Parlor and hospital were directly aft of the cabins in the bow section, which contained the forecastle. Amidships were 16 "Deluxe Cabins". The aft of Golden Deck had the ship's gym and spa area, and the poop deck and fantail. Ruby deck, the highest deck in the ship's hull, also had passenger cabins and 16 Deluxe Cabins below those on Golden Deck. Emerald deck had further cabins and the main entrance area of the Stella Solaris. The entrance area had recessed circular lighting inspired by 1950s Italian ocean liners. Sapphire Deck had the lowest passenger cabins on the ship, divided into two portions. The ship's cinema was located in the back, as was the Discothèque, a public room located underneath the cinema.
