Gabriela Mihalcea (née Margineanu; born 27 January 1964) is a Romanian former track and field athlete who competed in the high jump and pole vault.

Mihalcea began her career in the high jump and reached the peak of the national scene with victories at the Romanian Athletics Championships in 1983 and 1985, competing against Niculina Vasile and Alina Astafei.

[3] Following her return from her doping ban, she changed her focus to the pole vault, which was becoming an increasingly popular women's event (thought not yet part of international programmes).

At the competition she achieved a national record height of 4.05 m (13 ft 3+1⁄4 in), taking the bronze medal on countback to Germany's Christine Adams, though both were easily beaten by Icelandic teenager Vala Flosadóttir.

[4][5] The women's pole vault gradually began to be incorporated into major competitions and the standard of the athletes improved.

[10] Her masters marks were bettered by Stacy Dragila in 2008, but she remains the Romanian record holder.
