Convallarioideae is a monocot subfamily of the family Asparagaceae. It used to be treated as a separate family, Ruscaceae s.l., but this family was merged into Asparagaceae in the APG III system of 2009. Initially the name Nolinoideae was used, derived from the type genus Nolina. This name was supposed to have been published by Burnett in 1935. However, this has been shown to be an error, as Burnett based a subfamily on the Solanaceae genus Nolana not Nolina.

The subfamily includes genera that had been placed in a range of different families, including Ruscaceae s.s., Nolinaceae, Dracaenaceae, Convallariaceae and Eriospermaceae. Like many groups of lilioid monocots, the genera included here were once included in a wide interpretation of the family Liliaceae.
