A tiglon or tigon (not tigron) is a sterile hybrid cross between a male tiger (Panthera tigris) and a lioness (Panthera leo). Thus, it has parents with the same genus but of different species. The tiglon is not currently as common as the converse hybrid, the liger; however, in the late 19th and early 20th centuries, Gerard Iles wrote that he had been able to obtain three tiglons, but he had never seen a liger.
The tiglon's genome includes genetic components of both parents. Tiglons can exhibit observable characteristics of both parents: they can have both spots from the mother (lions carry genes for spots—lion cubs are spotted and some adults retain faint markings) and stripes from the father. Any mane that a male tiglon may have will appear shorter and less noticeable than a lion's mane and is closer in type to the ruff of a male tiger.
It is a common misconception that tiglons are smaller than lions or tigers. They do not exceed the size of their parent species because they inherit growth-inhibitory genes from the lioness mother, but they do not exhibit any kind of dwarfism or miniaturization; they often weigh around 180 kilograms (400lb).
A number of tiglons are currently being bred in China.

In Wild Cats of the World (1975), Guggisberg wrote that ligers and tiglons were long thought to be sterile; in 1943, however, a fifteen-year-old hybrid between a lion and an "Island" tiger was successfully mated with a lion at the Munich Hellabrunn Zoo. The female cub, although of delicate health, was raised to adulthood.
At the Alipore Zoo in India, a female tiglon named Rudrani, born in 1971, was successfully mated to an Asiatic Lion named Debabrata. The rare, second generation hybrid was called a litigon. Rudhrani produced seven litigons in her lifetime. Some of these reached impressive sizes—a litigon named Cubanacan (died 1991) weighed at least 363 kilograms (800lb), stood 1.32 metres (4.3ft) at the shoulder, and was 3.5 metres (11ft) in total length.
Reports also exist of the similar titigon, resulting from the cross between a female tiglon and a male tiger. Titigons resemble golden tigers but with less contrast in their markings. A female tiglon born in 1978, named Noelle, shared an enclosure in the Shambala Preserve with a male Siberian Tiger called Anton, due to the keepers' belief that she was sterile.
In 1983 Noelle produced a titigon named Nathaniel. As Nathaniel was three-quarters tiger, he had darker stripes than Noelle and vocalized more like a tiger, rather than with the mix of sounds used by his mother. Being only about quarter-lion, Nathaniel did not grow a mane. Nathaniel died of cancer at the age of eight or nine years. Noelle also developed cancer and died soon after.
