Damascenones are a series of closely related chemical compounds that are components of a variety of essential oils. The damascenones belong to a family of chemicals known as rose ketones, which also includes damascones and ionones. beta-Damascenone is a major contributor to the aroma of roses, despite its very low concentration, and is an important fragrance chemical used in perfumery.

The damascenones are derived from the degradation of carotenoids.

In 2008, (E)-β-damascenone was identified as a primary odorant in Kentucky bourbon.
