倭狨（学名Callithrix (Cebuella) pygmaea）是生活在巴西西部、哥伦比亚西南、厄瓜多尔尔西部和秘鲁东部雨林冠层的一种猴类。它们是体型最小的灵长类动物之一，体长大约只有14到16厘米（除去约15到20厘米的尾巴）。雄性体重140克，雌性体重120克。虽然在2003年发现了体型更小的新物种倭狐猴，但倭狨仍然是最细小的猴类。

The pygmy marmoset (Cebuella pygmaea) is a small New World monkey native to rainforests of the western Amazon Basin in South America. It is notable for being the smallest monkey and one of the smallest primates in the world at just over 100 grams (3.5 oz) (Madame Berthe's mouse lemur is smaller). It is generally found in evergreen and river edge forests and is a gum-feeding specialist, or a gummivore.
