description This paper provides data on non-native fungus-like organisms (<i>Oomycota</i>, kingdom <i>Stramenopila</i>), their diversity, and distribution in Lithuania and is an addition to a previously published checklist of alien true fungi (<i>Chytridiomycota</i>, <i>Ascomycota</i>, and <i>Basidiomycota;</i> kingdom <i>Fungi</i>). All available published data were summarized, and the analysis showed that approximately 25% of recorded Lithuania stramenopilous fungus-like organism species are alien. The compiled list represented herein includes 54 species of alien terrestrial and aquatic stramenopilous fungus-like organisms (<i>Oomycota</i>). Most alien <i>Oomycota</i> are obligate pathogens of terrestrial plants. Aquatic organisms are represented by one alien dangerous crayfish pathogen, <i>Aphanomyces astaci</i>, which is currently noted as extinct in Lithuania. The taxonomy of the listed alien species of <i>Oomycota</i> has been revised, and the species names have been adjusted to reflect current nomenclature changes. The taxonomical and ecological analysis demonstrated the prevalence of terrestrial parasitic <i>Peronosporales</i> reported in Lithuania <i>Oomycota</i> and the highest diversity of alien species belonging to the <i>Peronospora</i> genus. The chronology of appearance, distribution within the country, and current status of these non-native organisms were assessed, and some of the most economically or ecologically important harmful invasive species were discussed.
