Kohbar (also spelled Kohvar) painting is a traditional matrimonial wall painting practiced in the Mithila region of Bihar. It is created mainly in the bridal chamber during weddings and symbolizes fertility, union, prosperity, and divine blessings for the newlyweds.

Traditionally practiced by women from Maithil Brahmin, Kayastha, and other local communities, the art form is passed down through generations, preserved through ritual, memory, and practice.

Kohbar paintings often accompany Mithila weddings and remain an essential part of Maithili cultural heritage.
