Kiyoshi is a Japanese name with a calm and pure meaning, reflecting the kanji used to write it. In the United States, the name first appeared in records in 1910 and reached its peak popularity in 1923, though it has always been a rare choice. As of 2025, it ranks 8,243rd, with only 1 in approximately 189,786 newborns receiving the name, a rate that has remained stable over recent years. The name is almost exclusively used for boys, and while it has no top states for usage, it is most likely found among families with Japanese heritage or an appreciation for Japanese culture.

Kiyoshi is a Japanese masculine name derived from the adjective 'kiyoi' meaning 'pure, clean' or 'quiet, calm.' It is often written with kanji such as 清 (kiyoshi, 'pure') or 静 (kiyoshi, 'quiet').
