The Leidseplein is a square in central Amsterdam, the Netherlands. Lying in the southwest of the Grachtengordel district of Amsterdam, the Leidseplein is immediately northeast of the Singelgracht canal. It is situated on the crossroads of the Weteringschans, the Marnixstraat, and the Leidsestraat.
The Leidseplein is one of the busiest centres for nightlife in the city. Historically, the square was the end of the road from Leiden, and served as a parking lot for horse-drawn traffic. Today, modern traffic travels through the square and side streets are packed with restaurants and nightclubs. The Stadsschouwburg, a theater, is the most notable architectural landmark on the square, and the American Hotel is close by.
