Basem Abdullah Eltahhan (born 17 August 1982 in Alexandria, Egypt) is an Egyptian former professional snooker player.

In 2017, Eltahhan beat fellow countryman Wael Talaat 6–5 in the final of the African Championship.

Due to lack of sponsorship Eltahhan couldn't make his professional debut until the 2017 English Open.

[1] His only match win during the season came at the single-frame Shoot-Out event, although he impressed at the 2017 UK Championship, battling world number 1 Mark Selby before ultimately losing 4–6; Selby praised his opponent afterwards, saying that Eltahhan played like a top-32 player.

[2] Eltahhan failed to win a single match during the next season, which ended with a 10-0 whitewash at the hands of Liang Wenbo at the 2019 World Championship qualifying rounds, and thus was relegated from the tour.
