*Isaz is the reconstructed Proto-Germanic name of the i-rune ᛁ, meaning "ice". In the Younger Futhark, it is called Iss in Icelandic and isa in Old Norse. As rune of the Anglo-Saxon futhorc, it is called is.
The corresponding Gothic letter is 𐌹 i, named eis.
The rune is recorded in all three rune poems:

Angerboda spake:
Iceold, wisecold
Like your hearts was the realm before time
Tha var hann medh hrimthursum
The one who betrayed, the one that we hate
He tried to weaken our lands
with his pain aglow
But hear me brethren:
I see us rising, freezing
The wolf will swallow the sun
And the daughter in her womb
The moon will be retorn from the skies
Stars will fall
Earth will rive and Upheaven
Time of axes, time of shields
The storm of our hate
will stiffen it all
Those of ice spake:
Thurisaz we are
From the edge of the nine worlds we reign
A distant memory of our balanced domain
That shall be risen, rebuilt again
Lead: M.H.
Angerboda spake:
With his flaming sword he will ride from the past
Burning the worlds of men and gods
A darkening arson, leaving but cold
The dragon he flies, biting that eye
Wisecold, iceold
Our shadow will fill the night
And those still alive will hide as thralls
To the fear of the might of our evil
Those of ice spake:
Thurisaz we are
We roamed the dark before both Van and Dis
The woods will burn and the oceans will freeze
And all the living, growing, breathing will moulder to cease
