No, many animals produce hair that is suitable for spinning into yarns or thread and weaving into cloth. Any hair that is suitable for this use may properly be called wool.
Among other animals, wool is commonly obtained from:
Sheep
Goats
Rabbits
Camels
Musk Ox
American Bison
Llama
Alpaca
Vicuna
Guanaco
Yak
Wool is only produced by sheep - other animals produce fibre - cashmere goats produce cashmere, angora goats produce mohair and angora rabbits produce angora.
Llamas, alpacas, Vicunas, guanacos, sheep, cashmere goats and cashmere rabbits can give wool. Llamas, alpacas, Vicunas and guanacos have very little lanolin in their wool so those who are allergic to sheep's wool, can typically wear lama wool.
More properly, the raw material from which wool is spun is called fleece.
Sheep fibres or hair -- fleece -- that the animals produce is broadly termed 'wool'. You can read more, below.

Wool grows pretty much like the hair on your head does, only denser and finer. Animals that have wool are alpacas, lamas, and some types of sheep and goats.
Wool originates on animals that grow fleece.
