Lynden was begun in 1871 and established in 1874 by Holden and Phoebe Judson near the site of the Nooksack Indian village Squahalish (Nooksack: Sqwehálich). It was named by Phoebe Judson after the riverside town in Hohenlinden, a poem by Thomas Campbell, stating:
On Linden, when the sun was low,
All bloodless lay the untrodden snow;
And dark as winter was the flow
Of Iser rolling rapidly.
According to her book, A Pioneer's Search for an Ideal Home, she changed the spelling of "Linden" to be more visually appealing. The city was officially incorporated on March 16, 1891.
The city lies in a broad valley along the winding path of the Nooksack River, which empties into nearby Bellingham Bay.
