Sinterklaas in Sesamstraat is the title of special holiday episodes of Sesamstraat about Sinterklaas visiting the street accompanied by his good friends, the Zwarte Pieten (Black Petes), annually broadcast on 5 December. It was the idea of Aart Staartjes, actor, contributing editor and one of the directors of Sesamstraat to create these episodes.
The 1988 special aired again as a rerun in 1989 when, at the last minute, the tape of that year's special turned out to be missing. Since then, special care was taken in protecting – and copying – the specials.
The annual specials were cut due to budgetary reasons in 2005, but there are four episodes broadcasted on 1, 2, 3, and 4 December, and a compilation on 5 December. In 2010, there were eighteen special Sint episodes televised in the weeks before the compilation episode.
A new Sinterklaas episode was planned for 5 December 2011, but was cancelled at the last minute due to a live political broadcast.
