The wealthiest hockey player of all time in terms of cumulative net worth is legendary superstar Mario Lemieux, whose fortune extends far beyond his historic player earnings due to his shrewd business investments and ownership success. After a Hall of Fame playing career marked by incredible brilliance with the Pittsburgh Penguins, Lemieux famously rescued the franchise from bankruptcy by converting deferred salary owed to him into an equity ownership stake. When he later sold his majority control of the team for a staggering sum, his net worth skyrocketed into hundreds of millions of dollars, placing him comfortably at the pinnacle of hockey wealth above all other past and present players.
