The article is devoted to the study of the proper titles of feature films, through the prism of functioning. The topic under study has been updated by a number of factors, among which is the interest of linguists in the processes of nomination of films, in particular, the activation of typological studies of the proper titles of films as peculiar in terms of functions, structure, derivation, semantic and motivational basis of titles and the development of the Ukrainian film industry. We consider the proper names of feature films to be special, little-studied denotations. We recorded 364 titles of feature films that have been released since 2014.
 In the work, the main tendencies of the functioning of the proper titles of the feature film as a component of ideonymy have been traced. We studied proper names of this type from the point of view of the genre specificity of the researched material. In accordance with this, the following were established: the place and role of the concept of ‘film’ in Ukrainian onomastics, productive types of such names, their structural organization, word-forming potential and semantics of the creative basis of such names.
 Having analyzed such proper names, it is worth noting that, today, drama, in particular – comedy, is one of the most popular genres of Ukrainian cinema. In accordance with the structural organization of films, it is worth noting the high productivity of compound names. Such results, in our opinion, are undoubtedly related to the peculiarities of the functional load of the title-heading as a component of a complete work. Word formation is quite connected with the structure of the name, which is why productivity also gravitates towards lexical-semantic word formation due to the syntactic way of word formation. The semantics of the creative basis of proper names of this type are characterized by the productivity of appellative derivatives, in particular multi-component ones.
 In the future, we see the need to study other classes of filmonyms, as special structural elements of the onymic space of the modern Ukrainian literary language.
