The black-and-red broadbill is found in Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Singapore, Thailand, and Vietnam. In peninsular Thailand, it has vanished locally from some areas. It was also common in Singapore until the 1940s, after which it was not recorded until 2004, and then 2020. It mainly inhabits riparian forest edges up to altitudes of 300 m (980 ft) throughout its range, although it can sometimes be found up to altitudes of 900 m (3,000 ft) m. In areas further downstream, it inhabits screw-palm swamps near the edges of mangroves. In areas affected by heavy land-conversion, it inhabits rubber plantations and coconut groves or orchards that have water channels. It has also been observed in peat swamp forest, but rarely enters closed-canopy forest. It can adapt quite well to disturbed habitat, surviving in secondary forest that has some tall trees remaining, as well as secondary vegetation with clumps of forest in pastureland. It also inhabits seriously degraded habitats along rivers.
