The following link provides charities working to provide assistance to Ukraine.

Charity Watch

These are my personal favorites:

(1) Lutheran World Relief

(2) Doctors without Borders

(3) Care

(4) Catholic Relief Services

(5) International Rescue Mission

(6) Mercy Corp

(7) Save the Children

(8) Unicef

(9) International Committee of the Red Cross

I like to donate to the International Committee of the Red Cross, instead of the American Red Cross, in hopes that my contribution will go to help Ukraine.
