Lazio comprises a land area of {{convert|17,242|km2|sqmi|abbr=on}} and it has borders with [[Tuscany]], [[Umbria]], and [[Marche]] to the north, [[Abruzzo]] and [[Molise]] to the east, [[Campania]] to the south, and the [[Tyrrhenian Sea]] to the west. The region is mainly hilly (56%) and mountainous (26%), with some plains (20%) along the coast and the Tiber valley.

The coast of Lazio is mainly composed of sandy beaches, punctuated by the headlands of [[Cape Circeo]] (541 m) and [[Gaeta]] (171 m). The [[Pontine Islands]], which are part of Lazio, are off Lazio's southern coast. Behind the coastal strip, to the north, lies the [[Maremma]] Laziale (the continuation of the Tuscan Maremma), a coastal plain interrupted at [[Civitavecchia]] by the [[Tolfa Mountains]] (616 m). The central section of the region is occupied by the [[Roman Campagna]], a vast [[alluvial plain]] surrounding the city of Rome, with an area of approximately {{convert|2100|km2|0|abbr=on}}. The southern districts are characterized by the flatlands of [[Agro Pontino]], a once swampy and [[malaria]]l area, that was [[land reclamation|reclaimed]] over the centuries.

The [[Preapennines]] of Latium, marked by the [[Tiber Valley]] and the [[Liri]] with the [[Sacco River|Sacco]] tributary, include on the right of the Tiber, three groups of mountains of volcanic origin: the [[Volsini]], [[Monti Cimini|Cimini]] and [[Monti Sabatini|Sabatini]], whose largest former craters are occupied by the [[Lake Bolsena|Bolsena]], [[Lake Vico|Vico]] and [[Lake Bracciano|Bracciano]] lakes. To the south of the Tiber, other mountain groups form part of the Preapennines: the [[Alban Hills]], also of volcanic origin, and the calcareous [[Monti Lepini|Lepini]], [[Ausoni Mountains|Ausoni]] and [[Aurunci Mountains]]. The Apennines of Latium are a continuation of the Apennines of Abruzzo: the Reatini Mountains with [[Terminillo]] (2,213 m), Mounts Sabini, [[Monti Prenestini|Prenestini]], [[Monti Simbruini|Simbruini]] and [[Monti Ernici|Ernici]] which continue east of the Liri into the [[Mainarde Mountains]]. The highest peak is Mount Gorzano (2,458 m) on the border with Abruzzo.

=== Climate ===

The region's [[climate]], monitored by several dozen meteorological stations (many of which managed by the Lazio Regional Hydrographic and Mareographic Office), shows considerable variability from area to area. In general, along the [[coast]], there is a [[mediterranean climate]], the temperature values vary between {{convert|9|–|10|C|F}} in January and {{convert|24|–|25|C|F}} in July.
Towards the interior, the climate is more [[Continental climate|continental]] and, on the hills, winters are cold and at night, temperatures can be quite frigid.

With particular regard to the [[sunshine duration]], it should also be noted that, among the regional capital cities in Italy, Rome is the one with the highest number of hours of [[sunshine]] and days with clear skies during the year.
