Satire is a genre of the visual, literary, and performing arts, usually in the form of fiction and less frequently non-fiction, in which vices, follies, abuses, and shortcomings are held up to ridicule, often with the intent of exposing or shaming the perceived flaws of individuals, corporations, government, or society itself into improvement. Although satire is usually meant to be humorous, its greater purpose is often constructive social criticism, using wit to draw attention to both particular and wider issues in society.

कटूपहास या तन्ज़ ऐसे व्यंग्य को कहते हैं जिसमे किसी व्यक्ति, समाज, संस्था या राष्ट्र की बुराइयों की निंदा छुपी हो। तन्ज़ का ध्येय अक्सर शर्मिन्दगी की भावना के ज़रिये बुराइयों के प्रति जागरूकता लाना होता है ताकि उनमें सुधार हो सके. कटूपहास को अंग्रेज़ी में 'सैटाइअर' कहा जाता है।
