Sardines are small, nutrient-dense, oily epipelagic fish belonging to the family Clupeidae, widely consumed canned or fresh across the United States, Canada, the United Kingdom, Australia, and New Zealand. A 100-gram serving of Atlantic sardines canned in oil (drained solids with edible bones) supplies approximately 208 calories and 24.6 grams of high-quality complete protein, along with significant quantities of marine omega-3 fatty acids, bioavailable calcium, vitamin D, vitamin B12, and selenium.

Because whole sardines are typically processed and eaten with soft, edible bones, they offer an exceptional dietary source of non-dairy calcium and essential minerals. The baseline nutritional values detailed on this page represent canned Atlantic sardines in oil (drained solids with bone), the most accessible and widely tracked commercial form. Differences found in fresh sardines or sardines packed in water or tomato sauce are covered in dedicated sections below.
