Keiko is a feminine Japanese given name. Keikō (景行), with a long "o", is the name posthumously given to Emperor Keikō.

Possible meanings

As with many Japanese names, Keiko can be written using a number of different kanji. Some of the most common ways^{[citation needed]} of writing Keiko (and the most representative meanings of the respective kanji) are:

• 恵子 — "lucky child"
• 敬子 — "respectful child"
• 景子 — "sunlight/view/scenic child"
• 桂子 — "katsura tree child"
• 圭子 — "blessed child"
• 慶子 — "happy child"
• 啓子 — "open (one's eyes)/express/spring (season) child"
• 硅子 — "silicon child"

The suffix ko (子) implies the name is female and the name is almost never given to males. Much less commonly, Keiko can also be written as 螢子, 輕子, or 軽子.
