The titis, or titi monkeys, are the New World monkeys of the subfamily Callicebinae, which contains three extant genera, Cheracebus, Callicebus, and Plecturocebus. This subfamily also contains the extinct genera Xenothrix, Antillothrix, Paralouatta, Carlocebus, Lagonimico, and possibly also Tremacebus.

Titis live in South America, from Colombia to Brazil, Bolivia, Peru and northern Paraguay.

Depending on species, titis have a head and body length of 23–46 centimetres (9.1–18.1 in), and a tail, which is longer than the head and body, of 26–56 centimetres (10–22 in). The different titi species vary substantially in coloring, but resemble each other in most other physical ways. They have long, soft fur, and it is usually reddish, brownish, grayish or blackish, and in most species the underside is lighter or more rufescent than the upperside. Some species have contrasting blackish or whitish foreheads, while all members of the genus Cheracebus have a white half-collar. The tail is always furry and is not prehensile.

Diurnal and arboreal, titis predominantly prefer dense forests near water. They easily jump from branch to branch, earning them their German name, Springaffen (jumping monkeys). They sleep at night, but can also take a midday nap.

Titis are territorial. They live in family groups that consist of parents and their offspring, about two to seven animals in total. They defend their territory by shouting and chasing off intruders, but rarely engage in actual fighting. Their grooming and communication is important for the co-operation of the group. They can typically be seen in pairs sitting or sleeping with tails entwined.
