Teun Mulder is a Dutch professional poker player, not to be confused with the Netherlands' world champion cyclist of the same name. Mulder has more than $6 million in online poker tournament winnings, the bulk of which stems from his play at PokerStars, where he is known as "tinnoemulder."

Mulder has online poker tournament cashes dating back to 2013 but it is in recent years where the Dutchman's skills have been there for all to see. In 2020, Mulder won a $10,300 Spring Championship Of Online Poker (SCOOP) event for $113,785, a $5,200 Blowout Series title for $211,740, and was the third-place finisher in the $5,200 World Championship Of Online Poker (WCOOP) for a career-best $762,169. He added a second SCOOP title to his long list of poker accomplishments in 2021, taking down the $5,200 High Roller for $247,089.

Mulder's first recorded live cash came in August 2017 when he finished fourth in the €1,650 WSOPC Rotterdam Main Event for €31,214. Although Mulder does not play all that many live events, his results are incredible. At the time of writing, nine of Mulder's 35 live scores are worth six figures or more (he has two hauls of more than $1 million).

In 2020, Mulder finished second in the online edition of the $10,300 WPT World Championship Main Event at PartyPoker for $1,231,600, which remained his best-ever score for only two years.

In 2022, Mulder won a €25,000 High Roller at EPT Prague for €250,928 and followed that up with a seventh-place finish in the €5,300 EPT Prague Main Event a few days later for an additional €138,750. Less than a month later, Mulder won a $100,000 buy-in event at the Triton Poker Cyprus festival for a massive $1,940,000. The future is bright for this flying Dutchman.
