The taxonomy of the Gastropoda, as revised by Winston Ponder and David R. Lindberg in 1997, is an older taxonomy of the class Gastropoda, the class of molluscs consisting of all snails and slugs.^[1] The full name of the work in which this taxonomy was published is Towards a phylogeny of gastropod molluscs: an analysis using morphological characters.

This taxonomy assigns the various Gastropods into ranked categories, such as sub-orders and families, but does not address the classification of genera or individual species. This classification scheme is based on the molluscs' internal and external shapes and forms, but did not take into account any analysis of their DNA or RNA.

The classification below was the most recent until Bouchet and Rocroi published their revised taxonomy in 2005, which differs primarily in that the higher taxa are expressed as unranked clades where known, and termed "informal groups" or groups" where monophyly (a single lineage) has not yet been determined, and where polyphyly (more than one lineage) is suspected.

Ponder & Lindberg (1997) used only four families to analyze the Euthyneura. Further work by Dayrat & Tillier (2002)^[2] provided a great deal of detail about the relationships between within the Euthyneura.

Ponder & Lindberg (1997) did not use Linnean taxonomical ranks in their work, but the results of their paper were widely adapted and used with Linnean taxonomical ranks by other authors. An example of such taxonomy follows:
