V-型小行星或灶神星型是与灶神星，此型中体积最大的小行星（因而得名），有着相似光谱的小行星。

大部分成员的轨道元素类似于灶神星，不是足以成为灶神星族的成员，就是有着相似的离心率和轨道倾角，但是半长轴在2.18天文单位和3：1柯克伍德空隙的2.50天文单位。这表示大部分或全部的成员都来自灶神星外壳被撞击的碎片，也可能是历史上某个时刻一次很大的单一撞击事件造成的。在灶神星南半球的巨大撞击坑是此一撞击事件的主要候选场所。

V-型小行星与也是由岩石、铁和普通球粒陨石组成，与类似但更普通的S-型比较是中等的亮度。这种较为罕见的小行星类型，包含的辉石比S-型更多。

The spectra of the V-type asteroids, or vestoids, are similar to that of 4 Vesta, by far the largest asteroid in this class (hence the name). Approximately 6% of main-belt asteroids are vestoids.

A large proportion have orbital elements similar to those of 4 Vesta, either close enough to be part of the Vesta family, or having similar eccentricities and inclinations but with a semi-major axis lying between about 2.18 AU and the 3:1 Kirkwood gap at 2.50 AU. This suggests that most or all of them originated as fragments of Vesta's crust, possibly blasted out by a single very large impact at some point in its history. The enormous southern-hemisphere crater on Vesta, Rheasilvia, is the prime candidate for the impact site.
