La Fayette Grover (November 29, 1823 – May 10, 1911) was a Democratic politician and lawyer from the U.S. state of Oregon.

In 1854, he was appointed by the United States Department of the Interior a member of a commission sent to audit the claims from the Rogue River Indian War.

In 1857, he was a delegate to the Oregon Constitutional Convention, representing Marion County.

During the 1876 Presidential Election, Oregon's statewide result clearly favored Rutherford Hayes, but then-governor Grover claimed that elector John Watts was constitutionally ineligible to vote since he was an "elected or appointed official".

He died at his home in Portland, Oregon, on May 10, 1911, and was interred in River View Cemetery.
