A zabumba (Portuguese pronunciation: [zaˈbũbɐ]) is a type of bass drum used in Brazilian music. The player wears the drum while standing and uses both hands to play it.

The zabumba is usually between 16 and 22 inches in diameter and 5 to 8 inches tall. It has a wooden shell and may use either skin or plastic drum heads. The drum heads are tightened with metal parts and tension rods. The top head is often covered with tape or a cloth strip and struck with a mallet wrapped in cloth (held in the right hand) to create a low, deep sound with few extra tones. The bottom head is tightened more and struck with a thin, stick-like tool called a bacalhau (held in the left hand) to make a high, sharp sound with many extra tones.

The zabumba is built, tuned, and played in a way similar to bass drums from the eastern Mediterranean region, such as the davul.

The zabumba is used in music genres like forró, coco, baião, xaxado, and xote.
