Special elections to the Iowa Senate are called by the Governor of Iowa when a vacancy arises within the State Senate. If there is a vacancy in the Iowa General Assembly (i.e., the Iowa state legislature), the vacant seat must be filled by special election. If the vacancy occurs while the General Assembly is in session, the Governor must call within five days of the occurrence of the vacancy for an election as expeditiously as feasible, with a minimum 18-day notice. If the vacancy happens while the General Assembly is out of session, the special election must follow a 45-day notice, as long as the election does not coincide with a school election. All special elections must be held on a Tuesday.

- J. Donald Weimer won the general election in district 22 in 1970; however, Weimer did not take office. Robinson won a special election to the seat.
- James Turner won the general election in district 47 in 1972; however, Turner was deceased and this necessitated a special election.
- Senator Jim Lind (R) resigned in March 1997. In a special election in April 1997, Patricia "Pat" Harper (D) won a special election in Iowa Senate, District 13. The Iowa General Assembly's website notes Lind's resignation & Harper's elevation to the position, but the Iowa Secretary of State's website does not list election data for this seat as of April 11, 2020. I can only find an article in the Waterloo, IA local newspaper documenting the special election victory for Harper.
- Following the 2000 Census and 2002 redistricting, King would have been redistricted from state senate district 6 to district 26; however, he was elected to the US Congress in 2002, thus necessitating a special election in the Iowa Senate.
- Senator Ward had been redistricted from district 30 to 22 following the 2010 Census and 2011 redistricting process. She was running for re-election to in the newly-numbered district 22 when she died less than a month before the 2012 general election. She 'won' the 2012 general election for district 22 posthumously. Thus necessitating this special election. This explains why the election of Senator Schneider is considered a hold for Republicans, even though the immediately preceding senator from district 22 was technically a Democrat. Given the intricacies of renumbering after the redistricting process, he technically succeeded the posthumously re-elected Senator Ward.
- Democratic Senator J. Donald Weimer was redistricted from district 24 to 22 and Weimer won the 22nd district general election in November 1970. However, he did not take office. In a special election in December, Democrat Cloyd E. Robinson won and kept the seat for the Democratic Party.
