Manglesh Dosh, also known as Manglik Dosh or Manglik Dosha, is a term used in Vedic astrology to refer to the influence of the planet Mars (Mangal) on a person's horoscope. This dosha is believed to have significant implications for marriage and relationships.

Manglesh Dosh occurs when Mars is positioned in certain houses of the birth chart, particularly the 1st, 4th, 7th, 8th, or 12th houses.
