Dandelions are in the Asteraceae family, which is sometimes called the “daisy” family (as well as the “aster” or “sunflower” 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).
