Delta pyriforme is a species of potter wasp in the subfamily Eumeninae of the family Vespidae. They are distributed across Asia. Several populations are recognized:

• D. p. circinale (Fabricius, 1804)
• D. p. nigrocinctum Giordani Soika, 1993
• D. p. philippinense (Bequaert, 1928)
• D. p. pyriforme (Fabricius, 1775)

Delta pyriforme males have a yellow labrum and clypeus contrasting with the brown body colour. They also have a yellow pronotum and differ from Delta esuriens in lacking a yellow band on the petiole. Delta conoideum lacks yellow on the thorax.{{Cite journal |last1=Pannure |first1=Arati |last2=Belavadi |first2=Vasuki V. |last3=Carpenter |first3=James M. |date=2016 |title=Taxonomic studies on potter wasps (Hymenoptera: Vespidae: Eumeninae) of south India |url=http://biotaxa.org/Zootaxa/article/view/zootaxa.4171.1.1 |journal=Zootaxa |volume=4171 |issue=1 |pages=1 |doi=10.11646/zootaxa.4171.1.1 |pmid=27701247 |issn=1175-5334|url-access=subscription }}{{Cite journal |last1=Yamane |first1=Seiki |last2=Matsuura |first2=Hideaki |date=1991 |title=Establishment of Delta pyriforme (Fabricius) in the Bonin Islands, Japan (Hymenoptera, Eumenidae). |url=http://www.jstage.jst.go.jp/article/tropics/1/2+3/1_2+3_155/_article |journal=Tropics |volume=1 |issue=2/3 |pages=155–162 |doi=10.3759/tropics.1.155 |issn=0917-415X|doi-access=free }}
