The Senegal bushbaby (Galago senegalensis), also known as the Senegal galago, the lesser galago or the lesser bush baby, is a small, nocturnal primate, a member of the galago family Galagidae.

The name "bush baby" may come either from the animals' cries or from their appearance. They are agile leapers, and run swiftly along branches. They live in Africa south of the Sahara and nearby islands including Zanzibar. They tend to live in dry woodland regions and savannah regions. They are small primates (130mm and 95-300 grams) with woolly thick fur that ranges from silvery grey to dark brown. They have large eyes, giving them good night vision; strong hind limbs; and long tails, which help them balance. Their ears are made up of four segments that can bend back individually, to aid their hearing when hunting insects at night. Their omnivorous diet is a mixture of other small animals, including birds and insects, fruit, seeds, flowers, eggs, nuts, and tree gums.
