Laurens "Lau" van Ravens (18 September 1922 – 23 October 2018) was a Dutch international football referee, who featured at the 1970 FIFA World Cup.

At the 1970 World Cup, van Ravens officiated the first round match between West Germany and Morocco as well as the quarter-final match between the Soviet Union and Uruguay.

He started the second half of the former match not realizing that the Moroccan goalkeeper had not yet entered the pitch, and in the latter he mistakenly approved Uruguay's winning goal.

[1] His final game was Coen Moulijn's farewell match between Feyenoord and Uruguay on 9 June 1972.
