Dinuguan (Tagalog pronunciation: [dɪnʊgʊˈʔan]) is a Filipino savory stew usually of pork offal (typically lungs, kidneys, intestines, ears, heart and snout) and/or meat simmered in a rich, spicy dark gravy of pig blood, garlic, chili (most often siling haba), and vinegar.

[2] Dinuguan is also called sinugaok in Batangas, zinagan in Ibanag, twik in Itawis, tid-tad in Kapampangan, dinardaraan in Ilocano, dugo-dugo in Cebuano, rugodugo in Waray, sampayna or champayna in Northern Mindanao, and tinumis in Bulacan and Nueva Ecija.

[4] The Northern Luzon versions of the dish, namely the Ilocano dinardaraan and the Ibanag zinagan are often drier with toppings of deep-fried pork intestine cracklings.

The Itawes of Cagayan also have a pork-based version that has larger meat chunks and more fat, which they call twik.

[5][6] The dish is not consumed by religious groups that have dietary laws prohibiting the consumption of blood, most notably the indigenous Iglesia ni Cristo, Jehovah's Witnesses, Seventh-day Adventists, Muslims and Jews.
