The blue-backed manakin (Chiroxiphia pareola) is a small passerine bird which breeds in tropical South America, its range extending from Colombia and Tobago to southeastern Brazil. It is found in deciduous forests but not evergreen rainforests.
Like other manakins, the blue-backed manakin is a compact, brightly coloured forest bird, typically 13 cm long and weighing 19 g. The male is mainly black with a bright blue back, and pale orange legs. The crown is typically red, but yellow in C. pareola regina from the south-west Amazon.
The female has olive-green upperparts, and somewhat paler olive underparts. Young males are olive, but show a red cap and the start of a blue back as they mature.
The race endemic to Tobago, C. p. atlantica is larger and has more extensive red on the crown and blue on the back. It has been suggested that it represents a separate species, the Tobago manakin, but no major authorities recognize this today.
This species is similar to lance-tailed manakin, Chiroxiphia lanceolata, which breeds further north from northern Venezuela to Costa Rica, but the latter has elongated central tail feathers, and the male has a somewhat brighter blue back
