What is Haiku?

Haiku is a seventeen-syllable Japanese poetry with three lines of five, seven, and five syllables that generally evoke pictures of the natural world.

These are the rules for creating haiku:

There are a total of 17 syllables.Haiku is only three lines long.The first line of a Haiku typically contains 5 syllables, the second line has 7 syllables, and the third line has 5 syllables.

Avoid titles and rhyme (both of which are almost never used in haiku), as well as metaphor, simile, and most other rhetorical elements (they are often too abstract or detour around the directness exhibited in most good haiku).

Haikus are historically derived from the Japanese Hokku. Hokkus are group poetry that adhere to the 5/7/5 formula. They are intended to comment on the writers' season or surroundings and to generate some form of contrasting visual split by a kireji or "cutting word."
