The thick-billed honeyguide (Indicator conirostris) is a bird of the honeyguide family Indicatoridae. It has been reported interbreeding with the related lesser honeyguide (I. minor) and the two are sometimes treated as a single species. Clements merges it with the lesser honeyguide. The calls of the thick-billed honeyguide include a repeated "frip" which is similar to the call of the lesser honeyguide but deeper.
