Delairea aparadensis is a species of plant in the family Asteraceae that is native to Brazil and was described in 2021.

[2][3] Field work took place in southern Brazil from 2008 to 2020, where, in the latter year, a group of a scandent species of Senecioneae were discovered.

The species looked morphologically distinct from the Brazilian native members of the Senecioneae tribe that are present in South America and were more comparable to those in southern Africa.

[2] A rambling subshrub and a perennial herb growing around 40 cm to 150 cm tall, it features erect, glabrous, foliose, green stems with toothed, veined leaves which decrease in size towards the apex, and yellow discoid flowers.

[2] The species is found in Southern Brazil in regions such as, Aparados da Serra National Park, Morro da Igreja, in São Joaquim National Park, and at Urubici in Santa Catarina, where it is present in cloud forest environment, at elevations of 1700–1800 m. Critically endangered, it is found roughly in area of occupancy of less than 1 km2 due to the agricultural spread in Santa Catarina.
