The 1970 European Rowing Championships were rowing championships held on Lake Öreg in Tata, Hungary. There were five competitions for women only (W1x, W2x, W4x+, W4+, W8+); the events for men were contested two weeks later at the 1970 World Rowing Championships in St. Catharines, Canada, instead. As World Rowing Championships were still held at four-year intervals at the time, the European Rowing Championships were open to nations outside of Europe and had become to be regarded as quasi-world championships.
