Se'i or sei is an Indonesian smoked meat from Kupang, Timor island, East Nusa Tenggara, Indonesia.

In Kupang, people serve se'i with nasi panas (hot steamed rice), accompanied with sambal lu'at and jagung bose.

[4] Se'i has been historically made from Timorese deer (Cervus timorensis), but this practice has ceased due to a decline in population and its consecutive endangered status.

Beef and pork are largely the main ingredients of Se'i,[4] and are the preferred meat choices for both locals and tourists.

The number of restaurants serving se'i that have appeared outside of East Nusa Tenggara, such as in Jakarta and Bali, have also contributed to its popularity.
