Meaning and origin of Dia
Dia is a Spanish name that is usually said to mean “Spanish "day"; also a short form”.
Dia is a Spanish word meaning day, and it is also used as a short form of names like Diana, Nadia and Claudia. In Portuguese the same word also means day. As a given name it is short, bright and easy to say in many languages. It is said DEE-uh, with two syllables. Related names include Diana, Dina and Diya, a Hindi name meaning lamp, which sounds almost the same but comes from a different language. Because it is so short, it often works well with a longer middle name.
Popularity over time
Dia first appears in US Social Security records in 1948. It has never ranked in the national top 1,000, which keeps it genuinely uncommon. Its best national rank was #1,817 in 1968, and the most babies received it in 2015, when 62 were named Dia. In 2025, 34 babies were named Dia, and it ranked #4,197 nationally. That is 45% fewer than ten years earlier, so it is becoming less common.
Its national rank moved from #5,487 in 1950, #2,399 in 1980, #5,364 in 2000, #3,764 in 2010, and #4,197 in 2025. Of the 2,250 US girls named Dia since records began, 22% were born in the 2010s, its biggest decade. The 1970s come next, with 391 babies.
Other girls' names that peaked around the same time include Skylyn, Zahraa, Averee, Seren, and Kendalyn.
