What is the name of a poem that has one stanza?

There isn't a specific name for a poem with one stanza. Here are some ways to describe it:

* Single stanza poem: This is the most straightforward and accurate description.

* Mono-stanzaic poem: This uses a Greek-derived word for "one stanza."

* Short poem: This is a general term that could apply to a poem with one or more stanzas.

* Verse: This is a general term for a single line or a group of lines in a poem, so it could also describe a single stanza.

It's important to note that the number of stanzas doesn't define the poem's style or genre. A one-stanza poem can be a haiku, a limerick, a free verse poem, or any other form.
