Riserva naturale dell'Insugherata, Regional nature reserve in Metropolitan City of Rome, Italy.

Riserva naturale dell'Insugherata is a protected reserve covering about 740 hectares of green space between Via Cassia and Via Trionfale, with dense forests, waterways, and agricultural land. The terrain combines multiple habitat types that together form a connected ecosystem.

The reserve was established by regional law no. 29 of 6 October 1997 and is managed by Ente Regionale RomaNatura. Educational activities and guided tours were entrusted to Cooperativa Climax in 2000–2004 and 2008–2011. In May 2010, after six months of work, the Sentiero del Picchio was inaugurated, created by Cooperativa Climax with a contribution from RomaNatura.

The reserve takes its name from the cork oaks (sughere) growing within it. Educational activities and guided visits were run by the Cooperativa Climax between 2000 and 2004 and again from 2008 to 2011. In May 2010, after six months of work, the Sentiero del Picchio (Woodpecker Path) was opened, built by the same cooperative with funding from RomaNatura.

Official entrances number five: three from Via Trionfale (Via Castagnola, Via Rosa Gattorno, Via Conti) and two from Via Cassia (Via Panattoni, Via Angiulli). The Via Castagnola access is the most usable; others are sometimes closed or informally reopened by residents through private fences. The Picchio trail, opened in May 2010, is partly bordered by private property fencing, so access is limited.

The reserve takes its name from the many cork oaks (sughere) growing within it. Of the more than 630 plant species recorded, 44 are listed as peculiar to the reserve, and it holds the largest number of the herb species surveyed in Rome.
