Dandelions are in the Asteraceae family, which is sometimes called the 鈥渄aisy鈥 family (as well as the 鈥渁ster鈥 or 鈥渟unflower鈥 family). So, dandelions are distant relatives of daisies, but they are not considered a type of daisy, which most commonly refers to plants in the genus Leucanthemum (such as Shasta daisies or ox-eye daisies).
