France have dashed Wales' hopes of a back-to-back Grand Slam at the Six Nations after beating the defending champions 21-16 in Paris.
The visitors were leading 13-3 after 24 minutes, but by the break France had brought the score level at 13-13.
In the second half, Wales then fell behind and a penalty by Parra extended the lead to 21-13.
James Hook reduced the points difference with a penalty three minutes later but France held firm to win.
If Wales had won the match they would have equalled the tournament record of nine wins in a row.
After the match Wales coach Warren Gatland said: "With us 13-3 up and half-time coming we needed more accuracy.
"We've got to think about Italy [in Rome on 14 March] and getting some points on the board.
"Then it's Ireland at home we'll see if we can win the Championship on points."
