Two 2022 United States Senate elections in California were held concurrently on November 8, 2022, to elect a member of the United States Senate to represent the state of California. There were two ballot items for the same Class 3 seat: a special election to fill the seat for the final weeks of the 117th United States Congress (ending on January 3, 2023), and a general election for a full term (beginning on the same day), starting in the 118th United States Congress.

Incumbent Democratic Senator Alex Padilla was appointed in 2021 by Governor Gavin Newsom to fill the vacancy created by Kamala Harris's election to the vice presidency in 2020, and he sought a full term. A nonpartisan primary for each of the terms took place on June 7. The top two candidates in each primary, regardless of party, advanced to the special and regular general elections in November. With his advancement out of the primary, Mark P. Meuser ( ) became the first Republican since 2012 to advance to the general election, as both the 2016 and 2018 Senate elections solely featured Democrats as the top two candidates. This race was a rematch between the two, as both had previously run for the secretary of state in 2018. Padilla won both elections with more than 60% of the vote.

He became the first Latino elected to the U.S. Senate from California, and the first male elected to the Senate from California since Pete Wilson was re-elected in 1988 and the first male elected to the Class 3 Senate seat from California since Alan Cranston was re-elected in 1986. This was the first time since 1988 where both major party final candidates for a Senate seat in California were men and was also the first time where both major party candidates for the Class 3 Senate seat in California were men since 1986.

Primary elections Endorsements

Campaign Incumbent senator Alex Padilla was appointed to the job in January 2021 following Kamala Harris's election to the office of Vice President of the United States. Following his appointment, Padilla quickly began to focus on his 2022 election campaign, as the fact that he has not been elected to the position means that he has a relatively low profile. Padilla's election strategy focused on advocating for progressive policies and building ties with left-wing organizations that had a poor relationship with California's other Senator, Dianne Feinstein. The potential Democratic opponent to Padilla considered most likely to join the race was U.S. Representative Ro Khanna, a staunchly left-wing Democrat who rose to prominence as the co-chair of the Bernie Sanders 2020 presidential campaign, and who had a loyal base of support from California's Asian-American and Pacific Islander communities. On August 9, 2021, Khanna announced that he would be endorsing Padilla for election, which was viewed as likely ending any possibility that Padilla would face a serious Democratic opponent. It was noted by the San Francisco Chronicle that it was considered unlikely that Padilla would face any serious Republican opponent, as California's heavily Democratic lean caused potentially strong candidates, such as U.S. Representatives Mike Garcia and Young Kim, to prefer to remain in their positions rather than launch a long-shot Senate run.

In April 2022, billionaire businessman Dan O'Dowd entered the race, launching a $650,000 ad campaign. O'Dowd's goal with this ad buy, and with entering the race in the first place, was to "make computers safe for humanity" and draw the attention of the public and politicians to the dangers of Tesla's unfinished Full Self-Driving software being rolled out to 100,000 cars on public roads.
