Antennaria parlinii, known as Parlin's pussytoes, is a herbaceous flowering plant in the family Asteraceae. Like other species in the genus, the plant is dioecious. It is widespread across eastern and central Canada and eastern and central United States, from Manitoba to Nova Scotia south as far as Texas and Georgia.
Antennaria parlinii is an herb up to tall. Male and female flowers are borne on separate plants (also known as dioecy); in some populations all the plants are female. White flowers bloom April to June, with 4 to 12 or more flowerheads on a cluster at the top of the stems. The common name refers to the resemblance of the flowers to the toes of a cat. The basal leaves are long and up to wide. A. parlinii is very similar to the species Antennaria plantaginifolia (plantain leaf pussytoes), although the flowers of A. parlinii are larger.'
This species is found in Canada (Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia) and the United States (entirety of the Central United States and Eastern United States except for Florida). It grows in dry, rocky areas in full sun to partial shade. It prefers acid soil.

The specific epithet, parlinii, was named after John Crawford Parlin who recognized the uniqueness of this species. In English, the species is commonly known as Parlin's pussytoes.
, Plants of the World Online recognizes two subspecies for this taxon:
The two subspecies can be differentiated using the stems and basal leaves. A. p. subsp. fallax has glandless stems and basal leaves that are adaxially tomentose, while A. p. subsp. parlinii has stems with purple, glandular hairs and basal leaves that are adaxially glabrous.
