Naja nivea in a dark brown and yellow speckled pattern, not sufficiently aroused to display its hood

Cobra is the common name of various elapid snakes, most of which belonging to the genus Naja, all of which are venomous and many of which are capable of rearing upwards and producing a hood when threatened. All members of the genus Naja, the "true" cobras, rear and produce obvious hoods, though not all have equally broad hoods. Other "cobra" genera and species are as follows:

The following species are not in the genus Naja but are hooding, venomous members of the family Elapidae:

• The rinkhals, or ring-necked spitting cobra Hemachatus haemachatus, which spreads a broad, cobra-like hood
• The king cobra, Ophiophagus hannah, which has a narrower hood than most cobras
• The two species of tree cobra, Pseudohaje goldii and Pseudohaje nigra with only a slightly spreading hood
• The two species of shieldnose cobras, Aspidelaps lubricus and Aspidelaps scutatus with a narrower hood than most cobras

• The two species of black desert cobra, Walterinnesia aegyptia and Walterinnesia morgani, neither of which rears or produces a hood
• The so-called American cobra, the Eastern coral snake, Micrurus fulvius, which also does not rear or produce a hood

The false water cobra, Hydrodynastes gigas, is the only "cobra" which is not a member of the Elapidae. It does not rear, produces only a slight flattening of the neck, and is only mildly venomous.
