On July 26, 1976, the Libertarians started a petition drive so that their presidential candidate, Roger MacBride, could appear on the ballot. They were unsuccessful in gathering at least 6,300 signatures by September 28, but MacBride received 89 write-in votes (0.1%) in the general election.

1980s
On August 11, 1980, the Libertarians started a petition drive so that their presidential candidate, Ed Clark, could appear on the ballot. Around 11,000 signatures were collected and on September 18, the Secretary of State certified 6,522 of the signatures, which was more than the 6,469 required, allowing Clark to appear on the ballot as an independent candidate. Clark campaigned in Casper, Wyoming, and received 4,514 votes (2.6%) in the general election.

In 1984, four members of the Libertarian Party filed a lawsuit in the U.S. District Court in Cheyenne, Wyoming, to have eleven sections of Wyoming's election codes declared unconstitutional. Judge C. A. Brimmer ruled in favor of the Libertarians, but allowed Secretary of State Thyra Thomson to enforce the election code during the 1984 elections.

On February 8, 1986, the Libertarian and American parties of Wyoming merged to form the Wyoming American-Libertarian Party. However, on May 3, the party was dissolved after gathering 3,000 signatures, less than the 8,000 required to run candidates.
