Senecio rowleyanus, commonly known as string-of-pearls or string-of-beads, is a flowering plant in the daisy family Asteraceae. This plant was named after British botanist Gordon Douglas Rowley who specialized in Cactaceae and succulents. It is a creeping, perennial, succulent vine native to the drier parts of southwest Africa. In its natural environment its stems trail on the ground, rooting where they touch and forming dense mats. It often avoids direct sunlight by growing in the shade of other plants and rocks.

"String-of-beads" and several other common names are shared with Senecio herreianus, which has teardrop-shaped leaves, rather than spherical.
