The 1910–11 United States Senate election were held on various dates in various states.

However, some states had already begun direct elections during this time. Oregon pioneered direct election and experimented with different measures over several years until it succeeded in 1907. Soon after, Nebraska followed suit and laid the foundation for other states to adopt measures reflecting the people's will. By 1912, as many as 29 states elected senators either as nominees of their party's primary or in conjunction with a general election.

Quay was appointed to the Senate seat by the governor, but the Senate refused to seat him on the grounds that the governor lacked the constitutional authority to make the selection, and the seat remained vacant until the next meeting of the legislature, in 1901, when Quay was elected.
