This research was done in Sebeta Hawas district Oromia region, Ethiopia. A total of nine representative kebeles were selected purposely with the help of information acquired from the office of Agriculture and conservation of natural resource department of the district. Ten(10) household informants were selected randomly from each 9 representative kebeles (90) and all the Development Agents (10) were included as informants. In addition to the primary data sources obtained by close observation and interviews made with each informant (100 informants) secondary data sources were also obtained from written documents. Data obtained were entered into SPSS 2020 version and processed. Apart from this, data were analyzed using preference ranking and direct ranking matrix to identify the main invasive weeds and their impact on cultivated crops respectively. Cirsium vulgare, Setaria pumila, Phalaris paradoxa, Xanthium spinosum, Rumex crispus, and Argemone ochroleuca were identified as the prominent invader in the Sebeta Hawas district. These species were found spread and introduced to many ecosystems by wind(31%) that followed by animals(22%). Majority of them were observed growing in roadsides(17.8%) and non cultivated lands(17.8%). S.pumila that followed by P.paradoxa pose more impact on agricultural crops in varied degrees. Making awareness creation by Development Agents and district administrator for the community regarding the nature of each species, their spreading means and their preventive techniques are recommended. Further research at regional and national level on invasive plants is recommended so as to minimize further spread and complete removal of invasive species of the district
