The spider is black, and the female often kills and eats the male during/after mating, thus making herself a widow. This is a double meaning of "black," both the color, and black as a symbol of evil, as in "the black arts." This sense of evil is further reinforced by the fact that the black widow is venomous to humans.
Sometimes the male brings the female an insect when wanting to mate, so she won't be so hungry and maybe he won't die.

It's called "black" because the species L. mactans (the main species with which most people associate the name "black widow") is black. As for the word "widow" it comes from the belief that the female eats the male after copulation. That is generally not true, with the exception of 2 species: L. hasselti and L. katipo. Male spiders of those species in a way commit suicide during copulation, but that way they copulate longer. That gives them greater chance of fertilizing the female.

They are called black due to their black coloration, which is only disrupted by a red hourglass shape on their bellies - a warning for vertebrates that it is dangerous when provoked. It is called the widow because, like many spiders, it has a tendency to devour the male after mating.

The black widow spider (Latrodectus spp.) is a spider notorious for its neurotoxic venom. It is a large widow spider found throughout the world and commonly associated with urban habitats or agricultural areas. Although the name 'black widow spider' is most commonly used to refer to the three North American species best known for their dark coloration, black hair and red hourglass pattern, occasionally it is applied to several other members of the Latrodectus (widow spider) genus in which there are 31 recognized species including the Australian red-back, brown widow spider (sometimes called the gray widow), and the red widow spider. In South Africa, widow spiders are also known as the button spiders.

Currently, there are three recognized species of black widow found in North America: The southern black widow (L. mactans), the northern black widow (L. variolus), and the western black widow (L. hesperus). As the name indicates, the southern widow is primarily found (and is indigenous to) the southeastern United States, ranging from Florida to New York, and west to Texas, Oklahoma and they run particularly rampant in parts of Arizona.

The northern widow is found primarily in the northeastern US and southeastern Canada (only on the Bruce Peninsula), though its ranges overlap that of L. mactans quite a bit. The western widow is found in the western half of the United States, as well as in southwestern Canada and much of Mexico. Prior to 1970, when the current taxonomic divisions for North American black widows were set forth by Kaston, all three varieties were classified as a single species, L. mactans. As a result, there exist numerous references which claim that "black widow" (without any geographic modifier) applies to L. mactans alone. As common usage of the term "black widow" makes no distinction between the three species (and many laypersons are unaware of the differences between them), and as the three species have much in common, this article treats all three species of black widow equally. Except where otherwise indicated, the remainder of the article applies to all three of the above species.

the spider is named so because it kills its mate after copulation and becomes "widow"
