The Havana Brown was the result of a planned breeding between Siamese and domestic black cats, by a group of cat fanciers in England, in the 1950s. Early breeders introduced a Siamese type Russian Blue into their breeding. However, using current genetic testing, it is believed that almost none remain in the gene pool.

The Siamese cat is one of the first distinctly recognised breeds of Asian cat. Derived from the Wichianmat landrace, one of several varieties of cats native to Thailand, the original Siamese became one of the most popular breeds in Europe and North America in the 19th century. Siamese cats have a distinctive colourpoint coat, resulting from a temperature-sensitive type of albinism.

Suphalak cat, Siamese cat, Korat cat and Ninlachak cat in Tamra Maew (The Cat-Book Poems) are thought to originate from the Ayutthaya Kingdom (1351 to 1767 AD). Over a dozen are now kept in the National Library of Thailand.
While this show quality specimen from 1960 still exhibits relatively moderate characteristics, the breed standard was setting the stage for the modern Siamese, with its call for a "dainty, long and svelte" body, a long head that "taper[s] in straight lines from the ears to a narrow muzzle", "ears large and pricked, wide at the base" and tail "long and tapering".
