The Paishacha marriage () is a non-righteous form of marriage described in Hindu literature. When a man stealthily rapes a woman who is asleep, intoxicated, or mentally challenged, it is regarded as a marriage, though only to preserve the honour of the woman.

This is condemned in the Manusmriti as a sinful act.Manusmriti with the Commentary of Medhatithi by Ganganatha Jha | 1920 | 1,381,940 words | (https://www.wisdomlib.org/hinduism/book/manusmriti-with-the-commentary-of-medhatithi/d/doc199802.html) In modern times, this is classified as a form of date rape, and is a crime in most countries.
