Girl at Sewing Machine is an oil-on-canvas painting by the American artist Edward Hopper, executed in 1921, now in the Thyssen-Bornemisza Museum in Madrid, Spain.

It portrays a young woman sitting at a sewing machine facing a window on a beautiful sunny day.

The location appears to be New York City as is evident from the yellow bricks in the window.

[1] The exterior vantage point, although present, only aids in putting the interior activity in perspective.

Hopper's repeated decision to pose a young woman against her sewing is said to be a commentary on solitude.
