The Blue Bird (French: L'Oiseau bleu) is a 1908 play by Belgian playwright and poet Maurice Maeterlinck.

The play has been adapted for several films and a TV series In the opening scene, the two children gleefully describe the beautiful decorations and rich desserts that they see in the house of a wealthy family nearby.

When Tyltyl turns the diamond, the hall is bathed with a dazzling brightness, and the Luxuries run wildly in search of a dark corner where they may hide their ugliness from the ethereal light.

Also, he creates great happiness for another by giving his pet bird, which seems much bluer than before, to the sick child.

Celebrating the 100th anniversary of "Maurice Maeterlinck's greatest contemporary success The Blue Bird", as it was termed, his play was selected as the main motif of a high-value collectors' coin: the Belgian 50 euro Maurice Maeterlinck commemorative coin, minted in 2008.
