国歌
《最亲爱的圭亚那的山河》（Dear Land of Guyana， of Rivers and Plains）
Dear land of Guyana, of rivers and plains;
Made rich by the sunshine, and lush by the rains,
Set gem-like and fair, between mountains and seas,
Your children salute you, dear land of the free
Green land of Guyana, our heroes of yore,
Both bonden and free, laid their bones on your shore.
This soil so they hallowed, and from them are we,
All sons of one Mother, Guyana the free.
Great land of Guyana, diverse though our strains,
We're born of their sacrifice, heirs of their pains,
And ours is the glory their eyes did not see,
One land of six peoples, united and free.
Dear land of Guyana, to you will we give,
Our homage, our service, each day that we live;
God guard you, great Mother, and make us to be
More worthy our heritage, land of the free.
