Tamgho started 2011 in similarly strong form as he improved his world indoor record by a centimetre to win the French National Indoor Championships senior triple jump title for the third time with a jump of 17.91m. He improved his world indoor record one centimetre further at the 2011 European Indoor Championships, clearing 17.92 m in the triple jump final on both the second and fourth jumps, to take the gold medal with a new world indoor record in front of the home crowd at the Palais Omnisports de Paris-Bercy in Paris. The day before the triple jump final, Tamgho had narrowly failed to win the bronze medal in the long jump event of the 2011 European Indoor Championships. He finished the long jump final in 4th position, jumping only 2 cm less than the bronze medallist Morten Jensen.
