Amphimacer pentameter is a metrical line containing five amphimacers or cretic feet, each with a stressed-unstressed-stressed pattern. This creates a fifteen-syllable line with a highly regular, rolling rhythm marked as ′ ˘ ′ repeated five times. The form is exceptionally rare in English verse, as maintaining five consecutive cretic feet proves difficult given English's natural stress patterns and tendency toward iambic or trochaic rhythms. When employed, amphimacer pentameter produces a formal, almost ceremonial effect through its symmetrical structure, though its artificiality can make sustained use challenging for both poet and reader.

Amphimacer pentameter contains five amphimacer feet; its rhythmic weight makes it suitable for solemn or elevated passages, though rarely used in modern English poetry.
