The 58th United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It met in Washington, DC, from March 4, 1903, to March 4, 1905, during the third and fourth years of Theodore Roosevelt's presidency. The apportionment of seats in the House of Representatives was based on the 1900 United States census. Both chambers had a Republican majority.

This list is arranged by chamber, then by state. Senators are listed in order of seniority, and representatives are listed by district.
At this time, senators were elected by the state legislatures every two years, with one-third beginning new six-year terms with each Congress. Preceding the names in the list below are Senate class numbers, which indicate the cycle of their election, In this Congress, Class 1 meant their term ended with this Congress, facing re-election in 1904; Class 2 meant their term began in the last Congress, facing re-election in 1906; and Class 3 meant their term began in this Congress, facing re-election in 1908.
The names of members of the House of Representatives elected statewide on the general ticket or otherwise at-large, are preceded by an "At-large," and the names of those elected from districts, whether plural or single member, are preceded by their district numbers.
Many of the congressional district numbers are linked to articles describing the district itself. Since the boundaries of the districts have changed often and substantially, the linked article may only describe the district as it exists today, and not as it was at the time of this Congress.
The count below reflects changes from the beginning of the first session of this Congress.
