Klepáč (Polish: Trójmorski Wierch (Polish pronunciation: [trujˈmɔrski ˈvjɛrx]), until 1946 Klepacz; German: Klappersteine) is a peak in the Králický Sněžník Mountains range.

The names Klepáč and Klepacz are based on the clapping sound made by loose stones scattered on the peak in high winds or upon stepping on them.

The current Polish name Trójmorski Wierch means "Three Seas Peak" and is derived from this hydrological feature.

It is located in the Králický Sněžník Mountains on the Czech Republic–Poland border, in the territories of Dolní Morava and Gmina Międzylesie.

In the dry season, it is used by fire patrols to guard the surrounding forests.
