Hail! South Dakota,
A great state of the land,
Health, wealth and beauty,
That's what makes her grand;
She has her Black Hills,
And mines with gold so rare,
And with her scen'ry,
No state can compare.

Come where the sun shines,
And where life's worth your while,
You won't be here long,
'Till you'll wear a smile;
No state's so healthy,
And no folk quite so true,
To South Dakota.
We all welcome you.

Hail! South Dakota,
The state we love the best,
Land of our fathers,
Builders of the west;
Home of the Badlands,
And Rushmore's ageless shrine,
Black Hills and prairies, Farmland and Sunshine
Hills, farms and prairies, Blessed with bright Sunshine.
