Show me a source that says otherwise.

Also, fruit is a botanical term, and vegetable is not. Where is an online encyclopedia other than Wikipedia then? I'm sure the World Book Encyclopedia is where I first read about this.

EDIT:

The plant is generally much branched and has hairy, strongly odorous, feathery leaves. The drooping, clustered, yellow flowers are followed by red, scarlet, or yellow fruits, which hang from the many branches of one weak stem. The tomato fruit varies in shape from spherical to elongate and in size from 0.6 in. (1.5 cm) across to more than 3 in. (7.5 cm) across. The Spanish were bringing tomatoes from South America to Europe by the early 16th century; they were introduced to North America from Europe by the 1780s. Tomatoes are used raw, cooked as a vegetable or puree, and pickled, canned, and sun-dried. The term also applies to the fruit of L. pimpinelli folium, the tiny currant tomato.

Botanically speaking, a tomato is the ovary, together with its seeds, of a flowering plant, i.e. a fruit or, more precisely, a berry. However, from a culinary perspective the tomato is typically served as a meal, or part of a main course of a meal, meaning that it would be (and is) considered a vegetable.

This argument has led to actual legal implications in the United States, Australia and China. In 1887, U.S. tariff laws that imposed a duty on vegetables but not on fruits caused the tomato's status to become a matter of legal importance. The U.S. Supreme Court settled this controversy in 1893, declaring that the tomato is a vegetable, using the popular definition which classifies vegetable by use, that they are generally served with dinner and not dessert. The case is known as Nix v. Hedden (149 U.S. 304). While the Tomato can be classified as a fruit, it is officially categorized as a definite vegetable in the United States.

The USDA also considers the tomato a vegetable.

It should be noted that strictly speaking the holding of the case applies only to the interpretation of the Tariff Act of March 3, 1883 and not much else. The court does not purport to reclassify tomato for botanical or for any other purpose other than paying a tax under a tariff act.

In concordance with this classification, the tomato has been proposed as the state fruit of New Jersey. Arkansas takes both sides by declaring the "South Arkansas Vine Ripe Pink Tomato" to be both the state fruit and the state vegetable in the same law, citing both its botanical and culinary classifications.

Horticulturally speaking, the tomato is a vegetable plant. The plant is an annual and nonwoody. Most fruits, from a horticulture perspective, are grown on a woody plant (apples, cherries, raspberries, oranges) with the exception of strawberries.
