   The purpose of this article is to provide a new set which is supra semi preopen set via supra
topological space ( , ). with the help of some examples and properties. Also, some of their properties have been investigate. With we illustrate the relationships between this concept and supra preopen set (respectively, supra open set).
 Also, we define two spaces which are supra semi pre compact and supra semi pre Lindelöf spaces with the relationships between them. At the end of this work, we provide some examples, properties to support this work.
