Ilona Bruzsenyák (born 14 September 1950) is a Hungarian former track and field athlete who competed in the women's pentathlon, long jump and 100 metres hurdles.

Born in Pócsmegyer in Hungary's Pest County, she joined the Debreceni Egyetem athletics club in Debrecen before moving to Budapest and training with Újpesti TE.

[1] Her first national title came at the Hungarian Athletics Championships in 1971, where she won the women's pentathlon in a meet record of 4897 points, succeeding Margit Papp to the crown.

Her first final was the long jump and she produced a lifetime best performance of 6.65 m (21 ft 9+3⁄4 in) to break the Hungarian national record and take the gold medal ahead of Eva Šuranová of Czechoslovakia.

At the 1976 Montreal Games her decline on the international scene was evident as she failed to progress beyond the long jump qualifiers and dropped to sixteenth in the pentathlon rankings.
