ترکیب معطر یک ترکیب شیمیایی است که دارای عطر و بو است. یک ترکیب شیمیایی زمانی ترکیبی معطر است که ترکیب به اندازه ی کافی بخارشدنی و فرار باشد تا به قسمت بالای بینی و به دستگاه بویایی منتقل شود و موادی که تا به این اندازه بخار شدنی هستند معمولا دارای وزن مولکولی کمتر از ۳۰۰ می باشند. طعم بر هر دو حس چشایی و بویایی تاثیر گذار است، در حالی که رایحه یا عطر تنها حس بویایی را تحت تأثیر قرار می دهد. طعم ها معمولا به طور طبیعی شکل می گیرند در حالی که رایحه ها به صورت مصنوعی شکل می گیرند. ترکیب معطر در موادی چون خوراک، شراب، ادویهجات، ترشیجات، عطر، روغن رایحهدار و اسانس یافت می شود. بسیاری از ترکیب های معطر به هنگام واکنش های زیستشیمی طبیعی ساخته می شوند، واکنش هایی چون رشد میوه ها و یا تخمیر.
