There are many venomous snakes in the world, but the most dangerous one depends on how you define "dangerous." Here are some of the most venomous and deadliest snakes in the world, according to various sources:

• Inland Taipan: Arguably the most venomous and deadliest snake in the world, the inland taipan has the lowest LD50 rating out of all of the snakes found. It bites with only 44-110mg of venom per bite, and this is still enough to kill 289 humans.
• Black Mamba: Africas deadliest snake, the black mamba can kill a person with just two drops of venom. Its venom belongs to the class of three-finger toxins, meaning they kill by preventing nerve cells from working properly. The snakes are born with two to three drops of venom in each fang, so they are lethal biters right from the get-go. By adulthood, they can store up to 20 drops in each of their fangs.
• Saw-Scaled Viper: This snake may be the deadliest of all snakes, since scientists believe it to be responsible for more human deaths than all other snake species combined. Its venom, however, is lethal in less than 10 percent of untreated victims, but the snake’s aggressiveness means it bites early and often.
• Russells Viper: This species is considered one of the most deadly of the snakes. It kills more people in Sri Lanka, Burma, and India than any other snake. This snake is found in open grasslands across the Indian subcontinent, hunting in highly populated areas. Not only does this make Russell’s viper considerably dangerous due to its proximity, but it also has a bite to back it up.
• Eastern Brown Snake: Considered the second-most venomous terrestrial snake due to its venom potency, the eastern brown snake has a bite to be feared. Located in Australia, this snake is responsible for the most snakebite deaths in its region. As little as 3 mg of its venom kills the average human, but it also has to do with where this snake is located. It prefers to hunt in populated areas, which means it runs into people more often than it should.

Its important to note that while venomous snakes can be dangerous, they are not inherently aggressive and will usually only bite if they feel threatened or cornered. Its also worth noting that non-venomous snakes like pythons can kill humans, but this is excessively rare and mostly limited to interactions with pet constrictor snakes.
