The EuroBrun ER189B is the last Formula 1 single-seater entered by the EuroBrun Racing team in its final participation in the Formula 1 World Championship, in 1990.
It made its championship debut at the U.S. Grand Prix, succeeding the EuroBrun ER189. This single-seater, designed by George Ryton, Roberto Ori and Kees van der Grint, was directly inspired by its predecessor from the 1989 season. Piloted by Brazilian driver Roberto Moreno and Italian Claudio Langes, it was entered fourteen times but only managed to qualify twice, at the start of the season in the hands of Roberto Moreno.
After the European season, Walter Brun, owner of EuroBrun Racing, announced that he wished to devote himself solely to his commitment to the World Sports Car Championship, and withdrew for the remainder of the season. Fined $400,000 for his two forfeits, EuroBrun left Formula 1 for good. The ER189B is therefore the team's last Formula 1 single-seater.
