Seydou Doumbia (French pronunciation: [sɛdu dumbja]; born 31 December 1987) is an Ivorian former professional association footballer who played as a forward.

In 2010, he signed for CSKA Moscow for a reported fee of €15 million, where he won six domestic honours and was twice the Russian Premier League's top scorer.

He was transferred to Roma in 2015, and spent much of his tenure out on loan, including the 2016–17 season at Basel, where he won the league, Swiss Cup and was top scorer for a third time.

[7] On 30 July 2009, Doumbia scored the only goal of the game as he slotted the ball past goalkeeper Gorka Iraizoz to defeat Athletic Bilbao 1–0 in the first leg of their Europa League qualifying round tie at the San Mamés.

On 5 January 2010, Russian club CSKA Moscow completed the transfer of Doumbia on a five-year deal, for a reported fee of €15 million.

[19] In the next matchday, the Army Men travelled to the Stadio Renzo Barbera, where Doumbia netted another brace in a 3–0 win over Palermo on 21 October.

[27] The Ivorian striker added two more goals as CSKA defeated Turkish side Trabzonspor 3–0 on 18 October, to record the Russians first victory in Group B play.

[29] In their following league game against Spartak Nalchik on 28 October, Doumbia scored a seven-minute hat-trick to earn his side a 4–0 win, after his teammate, Vagner Love, had put the hosts up 1–0 in the 34th minute.

Doumbia opened the scoring against Internazionale on 7 December, guiding his side to a 2–1 away victory,[30] which secured a berth in the Round of 16 against Spanish club Real Madrid.

[35][36] Doumbia scored two first-half goals, the first of which was within two minutes of kick-off, as CSKA won 2–1 at Manchester City in the Champions League group stage on 5 November 2014.

[39] On 1 February 2016, it was confirmed that Newcastle United had signed Doumbia on loan for the remainder of the 2015–16 season, with an option to make the deal permanent in the summer.

[48] He made his debut for the Lisbon club on 11 August, replacing Daniel Podence for the final 25 minutes of a 1–0 home win over Vitória in the first game of the season.

Doumbia played rarely for Sporting, as manager Jorge Jesus considered him incapable of partnering the prolific Dutchman Bas Dost up front.

[50] On 13 December, in the last 16 of the Taça de Portugal, he scored a hat-trick as the Lions won 4–0 against third-tier Vilaverdense at the Estádio José Alvalade.

[62] At the 2015 Africa Cup of Nations finals, Doumbia scored les Éléphants' first goal of the tournament during their opening 1–1 draw with Guinea.
