The Boulevard Richard-Lenoir (French pronunciation: [bulvaʁ ʁiʃaʁ lənwaʁ]), running from the Bastille to the Avenue de la République, is one of the wide tree-lined boulevards driven through Paris by Baron Haussmann during the Second French Empire of Napoleon III.

The boulevard is named after François Richard-Lenoir [fr] (1765-1839) and Joseph Lenoir-Dufresne [fr] (1768-1806), business-partner industrialists who brought the cotton industry to Paris and northern France in the 18th and early 19th centuries. It is the site of a weekly art market and of a bi-weekly fruit and vegetable market that is one of the largest in Paris.

Georges Simenon's famous detective Jules Maigret is portrayed as living at 132 Boulevard Richard-Lenoir.
