Deroceras cecconii is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Agriolimacidae.

Although it was long considered a synonym of Deroceras panormitanum, a 2020 article establishes that it is a distinct species widely distributed in the central part of the Italian peninsula.

[9] New collections from the type locality of D. cecconii have now established that the animals described and figured by Pollonera are indeed distinct, based on mitochondrial DNA sequences and mating behaviour as well as genital anatomy.

[10] Deroceras cecconii occurs widely in the central part of the Italian peninsula, including at one locality in the Republic of San Marino.

The species typically is found under discarded rubbish and in leaf litter, in both synanthropic habitats and natural woodland.

[10] Deroceras cecconii is known to be adult in spring; its growth rate in the laboratory suggests that it may go through several generations in a year.
