Coreoidea is a superfamily of true bugs in the infraorder Pentatomomorpha which includes leaf-footed bugs and allies. There are more than 3,300 described species in Coreoidea.

There are five extant families presently recognized, but the Coreoidea as a whole are part of a close-knit group with the Lygaeoidea and Pyrrhocoroidea and it is likely that these three superfamilies are paraphyletic to a significant extent; they are therefore in need of revision and redelimitation.

The families are:

• Alydidae Amyot & Serville, 1843 – broad-headed bugs
• Coreidae Leach, 1815 – leaf-footed bugs and squash bugs
• Hyocephalidae Bergroth, 1906
• Rhopalidae – scentless plant bugs
• Stenocephalidae Amyot & Serville, 1843
• † Trisegmentatidae Zhang, Sun & Zhang, 1994
• † Yuripopovinidae Azar, Nel, Engel, Garrouste & Matocq, 2011
• † Pachymeridiidae Handlirsch, 1906
