<abstract>Political sentiment analysis aims to automatically identify opinions and attitudes expressed in political discourse on social media platforms. This paper presents an overview of the TamilPoliSent 2026 shared task on multiclass political sentiment analysis in Tamil, organized as part of DravidianLangTech@ACL 2026.
