Kabsa (Arabic: كبسة‎ kabsah) is a family of rice dishes that are served mostly in Saudi Arabia — where it is commonly regarded as a national dish — and the other Arab states of the Gulf. Kabsa, though, is believed to be indigenous to Yemen. In places like Qatar, the United Arab Emirates, Bahrain and Kuwait the dish is popularly known as machbūs (Arabic: مكبوس‎), but is served mostly in the same way.

These dishes are mainly made from a mixture of spices, rice (usually long-grain basmati), meat and vegetables. There are many kinds of kabsa and each kind has a uniqueness about it. Pre-mixed kabsa spices are now available under several brand names. These reduce preparation time but may have a flavour distinct from traditional kabsa. The spices used in kabsa are largely responsible for its taste; these are generally black pepper, cloves, cardamom, saffron, cinnamon, black lime, bay leaves and nutmeg. The main ingredient that accompanies the spices is the meat, such as chicken, goat, lamb, camel, or sometimes beef, fish, and shrimp. In chicken machbūs, a whole chicken is used. The spices, rice and meat may be augmented with almonds, pine nuts, onions and raisins. The dish can be garnished with ḥashū (Arabic: حشو‎) and served hot with daqqūs (Arabic: دقّوس‎) — home-made tomato sauce.
