Le Sueur was named in honor of the French explorer Pierre-Charles Le Sueur.
The community is known locally as the "Valley of the Jolly Green Giant". A large billboard, with the caption "Welcome to the Valley" and Green Giant logo, remains even after the company and Green Giant label were bought by Pillsbury in 1979. Now the Green Giant label is owned by General Mills and is canned in Montgomery, Minnesota. The old canning processing plant in Le Sueur was used until 1995. It is still used for Ag related research for corn varieties. Peas are no longer researched at the Le Sueur plant. The sugar snap pea variety was developed by a scientist at the Le Sueur plant.
William Worrall Mayo was an early resident who began his practice in Le Sueur. He eventually founded the world-famous Mayo Clinic in Rochester, Minnesota with his sons William and Charles. His old home, the Dr. William W. Mayo House, was restored to its mid-1800 appearance and turned into a museum; it, along with several other buildings in Le Sueur, is listed on the National Register of Historic Places.
