This page shows public proxy servers with IP addresses detected in Spain. The list may be short, so the practical goal is simple: test recent entries first and avoid relying on one visible proxy as if it were stable inventory.
If you want to compare Spain with other European locations, open the Europe proxy list.
For Spain, city and ISP are useful when more than one entry is available. A Madrid proxy and a Zaragoza proxy may belong to different networks, and the ISP column helps you see that difference before testing.
Check the protocol before copying the entry into your browser, app, proxy checker, or script. If the table shows HTTP, configure it as HTTP. Do not use SOCKS settings unless the table shows SOCKS4 or SOCKS5.
Use Last Checked and Uptime as your first filters. Speed can change quickly on public proxies, especially when the list is small. If one Spain entry fails, try another recent entry before moving to a different country.
