Eishōsai Chōki (Japanese: 栄松斎 長喜), also known as Momokawa Chōki, was a designer of ukiyo-e style Japanese woodblock prints who was active from about 1786 to 1808.
Chōki is best known for his pictures of beautiful slender women (bijin-ga), often with atmospheric backgrounds.
The artist signed most of his works Chōki (長喜), he also signed some work Eishōsai (栄松斎) or Shikō (子興).
Chōki specialized in depicting beautiful women and had a number of art names: works signed Chōki were in the style similar to that of Kiyonaga, and those signed Shikō that of Utamaro.
Amongst Chōki's more popular series were the Eight Views of Lake Ōmi (Ōmi hakkei) and the Eight Views of the Treasury of Loyal Retainers (Chūshingura hakkei).
