The Constitution of the State of Nevada is highest law within the U.S. state of Nevada and defines the structure, power, and limits of the state government and enumerates the basic rights and responsibilities of Nevada citizens, ratified. Subordinate to the Constitution of the United States, the Nevada Constitution requires it be a republic consisting of the bicameral Nevada Legislature, the Supreme Court of Nevada, and the office of Governor of Nevada.

On March 21, 1864, Congress passed an enabling act signed by President Abraham Lincoln authorizing the Territory of Nevada to be admitted as a state pending a ratified constitution. The people of Nevada approved the current Constitution on September 14, 1864, which was delivered to Congress over the course of two days by telegraph (the most expensive ever, at the time) costing USD $4,303.27 in 1864 (equivalent to $86,514 in 2024). Nevada became a state with the Nevada Constitution approved on October 31, 1864.

Nevada's first constitutional convention met in 1863. The draft as a result of that meeting was rejected by voters on January 19, 1864 because of the draft's taxation policies, particularly regarding mining activities.

The current constitution was written between July 4, 1864 and July 28, 1864 at a second constitutional convention in Carson City.at a convention on July 4 in Carson City.

Nevada's entry into full statehood in the United States was expedited. Union sympathizers were so eager to gain statehood for Nevada that they rushed to send the entire state constitution by telegraph to the United States Congress before the presidential election and they did not believe that sending it by train would guarantee that it would arrive on time. The constitution was sent over October 26–27, 1864, just two weeks before the election on November 7, 1864. The transmission took two days; it consisted of 16,543 words and cost $4,303.27 ($86,514 in 2024) to send. It was, at the time, the longest telegraph transmission ever made, a record it held for seventeen years, until a copy of the 118,000-word English Revised Version of the New Testament was sent by telegraph on May 22, 1881.

The document has two prefix provisions; a preamble; 19 articles (one having been repealed); and a suffix provision. The first prefix provision defines the requirement that the state have a constitutional convention. The second prefix provision declares certain mandates applicable to the state, including a prohibition on slavery, religious freedom, and declaring the public lands to be property of the United States. Later amendments changed this provision. The preamble reads: "We the people of the State of Nevada Grateful to Almighty God for our freedom in order to secure its blessings, insure domestic tranquility, and form a more perfect Government, do establish this Constitution."

The suffix provision provides for the election of delegates to the constitutional convention.
