Eschweilera is a genus of woody plants in the family Lecythidaceae first described as a genus in 1828.Martius, Carl (Karl) Friedrich Philipp von, ex Candolle, Augustin Pyramus de. 1828.

A phylogenetic study published in 2024 by Vargas et al. concluded that Eschweilera was polyphyletic. The authors proposed leaving the core Parvifolia clade in Eschweilera, and placing the Tetrapetala section of Lecythis in the new genus Imbiriba, the Integrifolia clade in the new genus Scottmoria, and Eschweilera amazoniciformis, an isolated sister lineage to Corythophora and Imbiriba, in the new monotypic genus Waimiria.Oscar M.
