Iva imbricata is a North American species of flowering plant in the aster family known by the common names dune marsh-elder and seacoast marsh elder. It is native to Cuba, the Bahamas, and coastal areas of the United States from Texas to Virginia. It is a low shrub, found on sand dunes and the upper beach. It is a highly salt tolerant plant, and is often the perennial plant closest to the ocean.

Iva imbricata is an important species for dune stabilization and can easily be propagated by cuttings. It sometimes grows up to 100 cm (40 inches) tall. It produces numerous flower heads in elongated arrays, each head with 2-17 disc flowers but no ray flowers.
