The least painful place on the body for a tattoo is behind the ear. According to Red Rose Magazine, a tattoo on the cartilage of the ear is also one of the least painful spots for ink.
No matter where the tattoo is located, it is always a good idea to use numbing cream to help manage the discomfort of the needle. As a general rule of thumb, areas of the body with more muscle and fat are the least painful spots for tattoos. In contrast, regions close to bones or nerve endings are the most painful places to get tattoos.
