Maria Albertina da Costa Dias Pereira (born 26 April 1965 in Miragaia) is a former Portuguese long-distance runner.

[3] Dias won the Eurocross meeting in 1991[4] and went on to take sixth place at the 1991 Cross Country Championships.

[2] Dias attended her second Olympics, the 1992 Barcelona Games and finished in 13th at the 10,000 metres final.

[2] She won the 1993 IAAF World Cross Country Championships long race the following year, becoming the first Portuguese woman to ever complete the feat.

[citation needed] She failed to match this feat at the 1993 World Championships in Athletics as she finished seventh in the 10,000 m.[2] A fifth-place finish at the 1994 IAAF World Cross Country Championships was enough for a team gold with Portugal, led by Conceição Ferreira.
