Rhein-Sieg-Kreis I was created in 1949, then known as Siegkreis. In the 1965 and 1969 elections, it was named Siegkreis I – Bonn-Land. It acquired its current name in the 1972 election. In the 1949 election, it was North Rhine-Westphalia constituency 11 in the numbering system. From 1953 through 1961, it was number 70. From 1965 through 1998, it was number 64. From 2002 through 2009, it was number 98. In the 2013 through 2021 elections, it was number 97. From the 2025 election, it has been number 96.

Originally, the constituency was coterminous with the Siegkreis district. In the 1965 through 1976 elections, it comprised the district of Landkreis Bonn as well as the modern municipalities of Bad Honnef, Königswinter, Niederkassel, Troisdorf, and Sankt Augustin from the Siegkreis district. It acquired its current borders in the 1980 election.
