番茄天蛾（学名：Manduca quinquemaculata），又名五点天蛾，是天蛾科的一种啡灰色的蛾物种，在美洲大陆大部分地区可见。它的幼虫是花园的主要虫害。

番茄天蛾很容易与烟草天蛾（Manduca sexta）混淆。两者长相相似，且属于同一属。其幼虫都以茄科植物的叶子为食，特别是同时也在番茄及烟草的叶上发现。番茄天蛾则有8个V形图案，而烟草天蛾两侧有7对斜线。此外，两者幼虫在背上的角的颜色也不同：番茄天蛾幼虫的角是黑色，但烟草天蛾幼虫的角是红色的。此外，番茄天蛾腹部上的五个点也是其标记。

The five-spotted hawkmoth (Manduca quinquemaculata) is a brown and gray hawk moth of the Sphingidae family. The caterpillar, often referred to as the tomato hornworm, can be a major pest in gardens. Tomato hornworms are closely related to (and sometimes confused with) the tobacco hornworm (Manduca sexta). This confusion arises because caterpillars of both species feed on the foliage of various plants from the family Solanaceae, so either species can be found on tobacco or tomato leaves, and the plant on which the caterpillar is found does not indicate its species. The larvae of these species can be distinguished by their lateral markings: Tomato hornworms have eight V-shaped white markings with no borders; tobacco hornworms have seven white diagonal lines with a black border. Additionally, tobacco hornworms have red horns; tomato hornworms have dark blue or black horns. Furthermore, the caterpillars can be distinguished from the larval stage onwards by the color of the horns on their back ends: M. quinquemaculata caterpillars have black horns, while M. sexta caterpillars have red horns. The moths can be distinguished by the number of spots on their abdomens, with M. quinquemaculata having, as its name suggests, five.
