Nude on the Chair or Nude with Chair (French: Nu ë la chaise) is an oil-on-canvas painting by the French Post-Impressionist painter Pierre Bonnard.

Created between 1935 and 1938, it is now held in the collection of the Bank of the Republic and exhibited at the Museo Botero, in Bogotá.

Fernando Botero, in hommage to Bonnard, interpreted Nude with Chair as an oil-on-canvas painting titled El baño (1999) which is also exhibited at the Museo Botero in Bogotá.

[3][4] Nude with Chair remained part of Bonnard's estate, and later his inheritance, until his passing in 1947.

[5] The painting was acquired by Fernando Botero from an anonymous art collector in Europe months before donating it to the Bank of the Republic to form the Museo Botero along with 207 other paintings and sculptures.
