Ola Williams Kamara (born 15 October 1989) is a Norwegian professional footballer who plays as a striker and is currently a free agent.

[3] He has previously played for Stabæk, Hønefoss, Strømsgodset, Molde, Austria Wien, TSV 1860 Munich, Columbus Crew SC, LA Galaxy, Shenzhen, D.C. United, Häcken and Vålerenga.

[9] Kamara made his debut for Stabæk in Tippeligaen at the age of 16,[10] when he replaced Somen Tchoyi as a substitute in the 2–2 draw against Lillestrøm on 1 October 2006.

[11] The next season, he joined the First Division side Hønefoss on a short-term loan, as a replacement for the injured Lars Lafton and Kenneth Di Vita Jensen.

[15] After Pedersen moved to Netherlands in August 2010, Kamara started to play regularly alongside Jo Inge Berget.

After a failed trial at West Ham United Kamara signed for Austria Wien in January 2014 but scored only two goals in 23 matches.

[24] On 4 August 2015, he scored a goal in 3-3 draw with Dinamo Zagreb in the second match of Third Qualifying Round UEFA Champions League.

After two successful seasons with Columbus, in January 2018 Kamara was traded to LA Galaxy in exchange for Gyasi Zardes and $400,000 in targeted allocation money.

[31] After an unsuccessful spell in China where he only made six appearances for Shenzhen, Kamara returned to Major League Soccer, joining D.C. United for a transfer fee of $2.5 million.

[36] DC had to travel to Toronto for the first round of the 2019 MLS Cup Playoffs and were defeated 5-1 after giving up 4 goals in AET to end their season.

He played in 22 of D.C.'s 23 regular season matches and started 17 but only managed to net four goals and did not provide a single assist.

[41] On the final day of the season Kamara scored a brace in a 3–1 win against Toronto FC which pushed him into a tie at the top of the 2021 MLS Golden Boot standings.

[43] That hurt was coupled by the fact that even though D.C. won their final match, other results did not go in their favor and they missed out on the 2021 MLS Cup Playoffs by one point.

Kamara made his debut for the Norway national team when he replaced Daniel Braaten in the 61st minute of the World Cup qualifier against Slovenia on 11 October 2013.

[47] In March 2018, Kamara earned a U.S. green card, which qualifies him as a domestic player for MLS roster purposes.
