Keijō (Japanese: 京城), or Gyeongseong (Korean경성), was an administrative district of Korea under Japanese rule that corresponds to the present Seoul, the capital of South Korea.

The name "Keijō" for "Seoul" remained in use in Japan for about a decade after the end of World War II. From the 1960s onwards, "Seoul" (ソウル - Souru) gained currency at the request of the South Korean government, and is the most commonly-used Japanese name today, with "Keijō" being relegated to historical or academic use only.
