Roma Alta, officially the State of Roma Alta, is a state located in south-central Cartadania. It had a 2020-census population of 9,402,613, making it the 13th-most populous state in Cartadania, as well as the 28th-most extensive. Combined with a density of 241 PD/km2, it is also the 3rd-most densely populated state in Cartadania. The state capital is Arranda, located in the state's central valley, while Cagliasi, is the state's largest city and is located along the state's short coastline. Greater Cagliasi is the most populous urban region, with about 3.5 million residents, comprising a third of the state's population.

The area that is present-day Roma Alta was first inhabited by Cartic peoples starting around 3,000 years BC, with the Linaca being the dominant group when Latins finally arrived in the early 4th century BC. Its position across the Turian mountains and so far south along the Bay of Verona made it of little interest to Republic-era Caphiria, thus it lacked true inland settlements until the Magna Discordia when Cartadania separated from Caphiria, taking the area with it.

Roma Alta's location in Cartadania makes it difficult to include it in a specific region. Because the regions exist merely as a consolidation and categorization of cultural similarities in the country, the state is not de jure part of any region. It is most commonly accepted, however, as a part of the Luson region. It's proximity to Turiana and Verona has fueled its rapid growth and suburbanization in the second half of the 20th century. With the turn of the 21st century, its economy increasingly diversified, with major sectors including biotechnology, pharmaceuticals, specialized agriculture, and informational technology. Roma Alta remains a major destination for immigrants from Caphiria, with one of the most multicultural populations in Cartadania. Echoing historic trends, the state has increasingly re-urbanized, with growth in the cities outpacing the suburbs since 2000. Roma Alta is one of the wealthiest states in Cartadania, with the seventh highest median household income in 2023. Almost one-tenth of all households, or over 341,000 of 3.5 million, are millionaires. Roma Alta's public school system consistently ranks at or among the top of all Cartadanian states.
