This study aims to provide an overview of the global research landscape related to forensic linguistics. Forensic linguistics is defined as the application of linguistic knowledge within legal contexts, offer unique and powerful tools to assist in resolving issues related to court proceedings. To achieve the research objectives, a thematic literature review method combined with statistical techniques was employed to analyze 34 relevant publications sourced from the Scopus database. The study highlights key aspects such as reputable authors, outstanding works, annual publication trends, and the core content of the published books. The findings provide a global overview of forensic linguistics and reveal four trends: discourse analysis in forensic contexts; corpus-based approaches to legal investigations; language-as-evidence with practical implications for courts; and additional aspects of legal language. Consequently, near-term directions to improve Vietnam’s forensic linguistics scholarship are proposed. The findings not only offer a comprehensive view of the current state of forensic linguistics research worldwide but also facilitate access for scholars in Vietnam to engage with and develop relevant studies in this field. This opens new avenues for research and contributes to enhancing the quality of forensic linguistics scholarship in Vietnam in the future.
