The 1968 United States Senate elections were elections for the United States Senate which coincided with the 1968 presidential election. Richard Nixon only won the presidential election narrowly, but the Republicans picked up five net seats in the election (not including two appointments that turned seats over to Republicans in the same year).

Republicans won open seats in Arizona and Florida and defeated Democratic incumbents Joseph S. Clark of Pennsylvania, Daniel Brewster of Maryland, A. S. Mike Monroney of Oklahoma and Wayne Morse of Oregon, as well as taking the seat of Frank J. Lausche of Ohio, who had been defeated in a primary by John J. Gilligan. Democrats won an open seat in Iowa as well as taking the seat of Thomas Kuchel of California, who had been defeated in a primary by Max Rafferty.

In addition, Republican Charles Goodell was appointed in September to the seat of assassinated presidential candidate Robert F. Kennedy of New York, and Ted Stevens was appointed in December to the seat of deceased Bob Bartlett of Alaska, bringing the net shift up to seven, although Democrats continued to control the chamber 57-43.
