Per the 2020 Census, its population was 107,819.[1] Its county seat is Rockwall.[2] The county and city are named for a wall-like subterranean rock formation that runs throughout the county.
Rockwall County was formed in 1873 from portions of Kaufman County. It split off because access to the county seat of Kaufman was inconvenient. It was named for its county seat, Rockwall.

Politics
Prior to 1972, Rockwall County was a Democratic stronghold. The 1968 election was highly transitional for the county with Hubert Humphrey only winning with 39% of the vote thanks to the strong third-party candidacy of George Wallace. From 1972 on, the county has become a Republican stronghold. George H. W. Bush in 1992 has been the only Republican to fail to win a majority in the county since then, as the strong third-party candidacy of Ross Perot that year led him to a second-place finish in the county over national winner Bill Clinton. However, the county was represented in Congress by a Democrat as late as January 2004, when Representative and Rockwall resident Ralph Hall, a conservative Democrat, switched parties and became a Republican.
However, in recent years, especially as the Dallas-Fort Worth Metro area continues to grow and spill over into neighboring counties, the county's Republican bent has lessened a bit. Native son George W. Bush registered 78% of the vote here in 2004.
Local government
Rockwall County is divided into four precincts, each represented by a County Commissioner.
As of the most recent elections in 2020, all four Commissioners are Republicans.
