Romnalda is a genus of monocotyledonous plants in the family Asparagaceae, subfamily Lomandroideae. (They have also been placed in the Xanthorrhoeaceae.) As of December 2013 four formally named species are known and accepted by botanical science.

The name Romnalda is an anagram of Lomandra, a related though more common genus of hard–leaved lily-like plants. The genus Romnalda differs from Lomandra in growing exclusively in rainforests and having sparsely branched inflorescences with no spines.

Plants have strap-like leaves and grow up to one metre (3 feet) tall often with a trunk and stilt roots reminiscent of a miniature Pandanus. Species of Romnalda grow naturally in Queensland and Papua New Guinea.
