Oliver Solberg (born 23 September 2001) is a Swedish Norwegian rally driver who competes in the World Rally Championship (WRC) for Toyota Gazoo Racing WRT under the Swedish flag. The son of 2003 World Rally champion Petter Solberg and WRC Commission president Pernilla Solberg, he became the 2025 WRC2 champion alongside co-driver Elliott Edmondson, and achieved his maiden WRC overall victory at a one-off appearance at the 2025 Rally Estonia.

After winning multiple crosskarting championships in his early years, Solberg became the RallyX Nordic Champion in 2018 and the FIA ERC1 Junior Champion in 2020. He made his WRC debut at the 2019 Wales Rally GB. In 2022, Solberg had a permanent part-time seat at the top level of the WRC for the first time as the third driver for Hyundai Motorsport, driving the new Rally1 car. In 2023, Solberg returned to the WRC2 competition, winning his first points-scoring event at the 2023 Rally Sweden. He returned to the top level as a full-time driver in 2026.

Solberg was introduced to the world of the WRC before his first birthday, when he attended the 2002 Cyprus Rally to watch his father compete. His grandfather and uncle are also experienced rally drivers. Though a career in motorsport wasn't inevitable, as his parents encouraged him to also try football, ice hockey and other activities, he ultimately decided to pursue motorsport. By the age of eight he was competing in crosskarting, winning his first race. Over the next years he won multiple Norwegian and Nordic Crosskart Championships.

Solberg started his professional rally career in 2017 at 15 years old. Given his young age, one of the few places he was allowed to compete was the Latvian Rally Championship, though he was still too young to drive the road sections which resulted in him and his co-driver Veronica Engan swapping seats between stages. His first rally was Rally Alūksne in a Peugeot 208 R2 where he finished 2nd in his class. He finished the year with two wins. Solberg competed in his second season of the Latvian Rally Championship in 2018, where he finished 2nd in both the LRC3 and U28 categories behind European champion Mārtiņš Sesks.

After two years competing in the Latvian Rally Championship in the R2 class, Solberg stepped into R5 machinery for the 2019 season. He won 5 consecutive rallies, ultimately winning the Latvian Rally Championship in the Volkswagen Polo GTI R5. One of the rounds of the championship, Rally Liepāja, also counted for the European Rally Championship, meaning he won on his ERC debut against top-level international competition. He also drove six rounds of the American Rally Championship in a Subaru WRX STI, with a livery based on his father's iconic blue and gold WRC Championship-winning car. He claimed victory on only his second outing at the Olympus Rally, and achieved a total of 3 victories in 6 races in the 2019 ARA season.

Solberg made his WRC debut at the end of the season at 2019 Wales Rally GB in a Volkswagen Polo GTI R5, showing stage-winning pace but ultimately retiring from the rally. The same rally also marked his father's last WRC event as he signed off with a WRC2 class victory.

After making his WRC debut at the end of 2019, Solberg stepped up into a full WRC campaign in 2020 driving his own VW Polo R5, and also a partial campaign with Škoda Motorsport. The COVID-19 pandemic paused rallying for some time, but as the sport returned, he won the Rally Sweden Lockdown before heading into the FIA ERC and scoring a podium on his full tarmac debut before winning Rally Liepaja for the second year running. When the WRC restarted, Solberg scored his first WRC class win with a WRC3 victory at Rally Estonia. He followed it up with taking home the 2020 FIA ERC1 Junior Championship title.

For 2021, Solberg joined the reigning WRC champions, Hyundai Motorsport, with a plan to drive the full WRC-2 season. However, after his debut for the team at the 2021 Monte Carlo Rally driving the Hyundai i20 R5, he was unexpectedly offered the chance to make his top-level WRC debut in the Hyundai i20 Coupe WRC at the second round of the season, Arctic Rally Finland. He went on to finish 7th overall with several top 4 stage times. After a series of bad luck through the middle of the year while driving in the WRC2 class, Solberg ended the 2021 season back in the World Rally Car and finished fifth at the 2021 Rally Monza.
